FIELD OF THE INVENTIONThe present invention relates generally to an optical disk writer capable of writing to optical disks. More particularly, the present application involves an automatic optical disk writer that can write to a plurality of optical disks by automatically inserting and removing optical disks from a disk drive.
BACKGROUNDOptical disks are capable of storing digital data such as music, text or video. The data takes the form of depressions on the surface of the optical disk that can be read through the use of a laser. CD-R, CD-RW, DVD-RAM and DVD-Video are a few of the commonly employed optical disk formats. In order to impart data onto an optical disk an optical disk writer may be employed. In this regard, the user must open a drawer of the optical disk writer and place the optical disk thereon. The user will then close the drawer and execute a series of computer commands that cause a laser in the optical disk writer to interact with dye in the optical disk and form the aforementioned depressions that can be later read as digital data. Although described as being written through the use of a laser, other methods such as stamping are known for imparting data onto optical disks. Once the writing process is complete, the user must open the drawer of the optical disk writer and remove the optical disk therefrom.
In order to produce a large quantity of optical disks with desired data a large amount of labor must be employed. As such, automatic optical disk writers are known for creating multiple optical disks with minimum effort. Such devices employ mechanical mechanisms that automatically insert and remove the optical disks from one or more optical disk writers included in the device. Other automated processes such as application of printed labels to the disks can be incorporated into the device to further reduce the amount of labor associated with producing a volume of optical disks.
One such known automatic optical disk writer includes a magazine capable of holding a number of blank optical disks for writing. A tower with a vertical rod onto which an arm is positioned is also included. The arm can move up and down the vertical rod and is also arranged to be able to swivel about the vertical rod. In use, the arm can swivel about the vertical rod until it is positioned over the magazine of blank optical disks. The arm can then be moved down onto the top optical disk in the magazine and engaged therewith. In this regard, the arm can include a pick or other device capable of grasping and holding the optical disk. The disk can then be moved by the arm and placed into a reclosable drawer of an optical disk writer. The reclosable drawer can be automatically closed and a writing process may be performed on the optical disk. A second optical disk writer is also included so that a second writing can be performed on another optical disk that is subsequently placed therein through use of the same arm.
Once the optical disk is written thereon, the reclosable drawer is opened and the arm removes the optical disk and transports it to a printer located directly above the optical disk writers. A printed label can then be automatically applied to the optical disk. Subsequently, the arm may again be used to pick up and remove the optical disk from the printer. The arm may again be moved vertically and swiveled so that the optical disk is located above a spindle. The arm can release the disk onto the spindle for storage for later retrieval by the user. Control of the various components of the automatic optical disk writer can be achieved through the use of software and/or a microprocessor directly integrated into the writer.
The present application is directed towards an improved automatic optical disk writer that features components that exhibit reliability and that is arranged in a manner so as to enjoy more desirable spatial characteristics.

The present invention provides for an optical disk writer 10 that can be used to automatically write data to an optical disk 14. The optical disk writer 10 includes an arm 20 that is capable of moving the optical disk 14 from a first storage area 80 to a disk drive 12 and afterwards to a second storage area 82 once the desired data has been written to the optical disk 14. The arm 20 may be moved along a track 24 that includes a vertical portion 26, a horizontal portion 28 and a curved portion 30. The track 24 is arranged so that the arm 20 may move the optical disk 14 to locations of the optical disk writer 10 useful in the automatic writing process. In accordance with one exemplary embodiment, the arm 20 is arranged so that it is stationary with respect to rotation about a vertical axis 84 of the arm 20.
One exemplary embodiment of the optical disk writer 10 is shown in
A plurality of optical disks 16 can be located at a first storage area 80 of the optical disk writer 10. The plurality of optical disks 16 are optical disks that have not yet had data recorded thereto by the disk drive 12. As shown, the first storage area 80 is a magazine 34. The plurality of optical disks 16 rest on a support 92 of the magazine 34 and are contained by three columns 94. The support 92 can be made of plastic and may be attached to base 90. It is to be understood that the configuration of the first storage area 80 is but one possible configuration and that others are possible in accordance with further exemplary embodiments.
An arm 20 can be used to remove an optical disk 14 from the magazine 34.
A track member 22 is provided and is mounted onto base 90 and located adjacent the disk drive 12. Track member 22 defines a track 24 through which the arm 20 is disposed. Track 24 may be a slot and can have a vertical portion 26, horizontal portion 28 and a curved portion 30 that is intermediate the vertical and horizontal portions 26 and 28. The arm 20 can be configured to move along the track 24. Comparison of
Once writing is complete, the reclosable drawer 78 can be opened and the written to optical disk 14 can be removed by pick 32. The arm 20 can be moved along track 24 to an end 40 of the horizontal portion 28 as shown in
The track 24 is arranged to allow the arm 20 to move in a vertical direction and in a horizontal direction. The illustrated configuration allows the optical disk 14 to be properly positioned for automatic writing without requiring the arm 20 to rotate about a vertical axis 84. Therefore, in accordance with certain exemplary embodiments the arm 20 may be stationary with respect to rotation about the vertical axis 84 of arm 20. Axis 84 may be oriented in the same direction as spindle 36 and can be perpendicular to the direction of opening and closing of the reclosable drawer 78. It is to be understood, however, that other arrangements of the optical disk writer 10 are possible in which the arm 20 and/or track 24 can be variously arranged. For example, the track 24 need not be a slot in other exemplary embodiments but may instead simply be an edge of the track member 22 or other component or combination of components. Although shown as having a planar face 23, the track member 22 need not have a planar configuration in other embodiments. The track member 22 may have multiple tracks 24 in other exemplary embodiments. Further, it is to be understood that other arrangements of the optical disk writer 10 exist in which the track member 22 need not be present.
A bracket 46 is mounted onto the gear 42 and engages a sliding member 48. The bracket 46 is fixed onto gear 42 so that these two elements do not move with respect to one another. Sliding member 48 is in sliding engagement with bracket 46 and moves linearly therewith. Due to the fixed relationship between gear 42 and bracket 46 the sliding member 48 can also move linearly with respect to gear 42. The sliding member 48 is attached to arm 20 which extends through the track 24. It is therefore the case that rotation of gear 42 is translated into movement of arm 20 by way of the engagement between gear 42, bracket 46 and sliding member 48.
A portion of the outer perimeter of gear 42 includes spaced projections 62. The spaced projections 62 can all have the same size and configuration and may be spaced an identical distance from one another along the gear 42. As shown, the spaced projections 62 are formed integrally with the gear 42 but can be a separate component that is attached thereon in other variations of the optical disk writer 10. The spaced projections 62 may extend around any portion of the perimeter of gear 42. In accordance with certain exemplary embodiments the spaced projections 62 can extend 90° to 120° about the perimeter of gear 42. The spaced projections 62 may extend the same angular distance as does the internal teeth 60 in certain exemplary embodiments. A sensor 64 is included in the optical disk writer 10 and remains stationary with respect to the gear 42. The sensor 64 can be mounted onto the track member 22 or other component of the optical disk writer 10 so that the sensor 64 does not rotate with the gear 42 but instead remains stationary as the gear 42 rotates. The sensor 64 is used in order to assist in determining the rotational position of the gear 42. The sensor 64 is capable of sensing the passage of the spaced projections 62 therethrough. In one embodiment, the sensor 64 may emit a small beam of light into a receiving portion. Movement of the spaced projections 62, as a result of rotation of gear 42, thus causes the light to be interrupted to the receiving portion of sensor 64. The sensor 64 can thus provide information to a microprocessor 66 that can be used to determine the amount of rotation of the gear 42 and also its current position. Knowledge of the movement and position of gear 42 can allow the microprocessor 66 to ascertain the movements and position of arm 20 due to the relationship between gear 42, sliding member 48 and arm 20. As such, the spaced projections 62 allow for the position and movements of arm 20 to be known by the microprocessor 66 when conducting an automated process of writing to optical disks 14.
As previously discussed the arm 20 picks up and moves the optical disk 14 and releases the optical disk 14 at certain portions in the automated process. One or more wires 72 can be run from the microprocessor 66 or electronics associated with the microprocessor 66 to cause the pick 32 of arm 20 to engage and hold and to disengage and release the optical disk 14. A pair of clips 74 and 76 are attached to the sliding member 48 and hold the wires 72 and allow for their movement during rotation of the gear 42 and sliding of the sliding member 48. The wires are run from the clips 74 and 76 into the arm 20 for actuating the pick 32. Although a pair of clips 74 and 76 are shown, it is to be realized that other arrangements are possible in which the clips 74 and 76 are not present.
The microprocessor 66 is configured to orchestrate the automated writing process of optical disk 14 by causing motor 56 to rotate gear 42 and thus position arm 20 along track 24, causing pick 32 to pick up and drop off optical disk 14, open and close the reclosable drawer 78 of the disk drive 12, and to initiate the writing of data to the optical disk 14. It is to be understood that other control type elements may be used to accomplish some or all of the automated process. For instance, the optical disk writer 10 can be in communication with a computer that includes software capable of instructing the optical disk writer 10 to carry out some or all of the aforementioned actions. As such, various means of controlling the automated process exist in accordance with certain exemplary embodiments.
Also shown in
Rod 68 extends into arm 20 and is internally mounted by way of bearing 88. Rod 68 may thus be cantilevered off of sliding member 48 and can completely support the rest of arm 20. Alternatively, rod 68 may be supported at other locations in accordance with other exemplary embodiments. Pivotal mounting of rod 68 by way of bearing 88 enables other portions of arm 20, notably that which includes pick 32, to be capable of pivoting with respect to cantilevered rod 68. The pick 32 can rotate freely about rod 68 or may be urged into a particular position through a spring or some other return mechanism. Pick 32 can thus pivot about a horizontal axis 86 of arm 20. The pick 32 and associated portions of arm 20 can rotate completely about axis 86 or may be limited to some degree of rotation thereto. For example, pick 32 may rotate up to 300° about horizontal axis 86. Rotation of pick 32 about the horizontal axis 86 may be desirable in allowing for variances in positioning between the optical disk 14, pick 32, reclosable drawer 78 and other components of the optical disk writer 10 during operation. Other embodiments are possible in which the arm 20 is stationary with respect to the horizontal axis 86 thus causing pick 32 to likewise be stationary with respect to the horizontal axis 86.
