    Abstract: The present invention relates to a library system including a disc recording/reproducing unit, a disc container, and a disc transport unit for transporting a disc between the disc recording/reproducing unit and the disc container. In order to improve the reliability of the operation of moving the disc from the disc recording/reproducing unit to the disc transport unit, a disc transport controller determines the situation in both the disc recording/reproducing unit and the disc transport unit, and error-stops the operation according to the result of the determination. Alternatively, the disc transport controller retries the movement of the disc, by pulling the disc into the disc transport unit or returning the disc to the disc recording/reproducing unit, and by finely adjusting the relative positions of the disc recording/reproducing unit and the disc transport unit if necessary, in order to solve the problem of damage to a surface of the disc.

  • Patent number: 7356825
    Abstract: The disk carrying apparatus includes a lifting portion which carries a disk onto a turntable, a chuck which holds the carried disk on the turntable, and a third switch which detects an intermediate position between a holding operation start position where the chuck starts a disk holding operation and a holding operation end position where the chuck finishes the disk holding operation. After completion of an initial disk holding operation, the chuck returns to the intermediate position detected by the third switch and retries the disk holding operation.

  • Patent number: 7345960
    Abstract: A method of tray ejecting force control for a tray-type optical drive is disclosed. A preliminary input voltage is provided to a DC motor of the tray-type optical drive to perform a preliminary ejection of a tray-type optical drive tray during a preliminary time period. When the preliminary time period is shorter than a predetermined time period, a first voltage smaller than the preliminary input voltage is provided to the DC motor to eject the tray. Alternately, when the preliminary time period is longer than the predetermined time period, a second voltage greater than the first voltage is provided to the DC motor for to eject the tray.

  • Patent number: 7313066
    Abstract: A write once disc allowing management of a data area, a method of managing the data area of the write once disc, an apparatus recording data on the write once disc, an apparatus and method of reproducing data from a write once disc. The write once disc, includes a lead-in zone, a data area, and a lead-out zone. The write once disc includes a predetermined area storing area allocation information which indicates whether at least one section of the data area is allocated for disc defect management. In the disc and method, area allocation information specifying a structure of the data area is recorded on the disc, thus allowing a recording/reproducing apparatus to recognize the data area structure. Therefore, allocating areas, such as a spare area, for disc defect management other than an area for storing user data, to the data area is possible. The allocation of the areas for disc defect management to the data area enables effective use of the write once disc.

  • Patent number: 7301857
    Abstract: A method and arrangement remembers a last-played position of a recorded medium by associating an identification number with the medium and storing therewith in memory a last-play position of the medium. The identification number of the recorded medium is analyzed after re-insertion of the medium into the player and play is resumed at the last-play position when the identification number corresponds with the identification number previously stored in memory.

  • Patent number: 7269103
    Abstract: A tape-shaped switch (500) is provided on a base part (410). Coil springs (460) support a ring-shaped rotational drive section (450) on the position opposed to the switch (500), biasing the same away from the base part (410), so that the rotational drive section (450) may move toward and from the base part (410). First buffers are provided in association with the switches (501) of the tape-shaped switch (500), respectively. A flange (313) extends outward from the disc-shaped table plate (311) of a jog table unit (310) and is mounted on the rotational drive section (450). When the user depresses the jog table unit (310), moving the same downward, at least one of the switches (501) is closed. The motion of the jog table unit (310) is reliably detected because it is detected at a position outside that part of the jog table unit (310), which is depressed so that good feeling of the operation can be obtained.

  • Patent number: 7266053
    Abstract: The present invention discloses a tray-out control method for moving out a loading tray of an optical drive. A first forcing function is applied to the loading tray to overcome a lesser magnetic attraction when an optical disk is placed on the loading tray. A second forcing function is applied to the loading tray to overcome a greater magnetic attraction when the optical disk is not placed on the loading tray. A maximum value of the second forcing function is larger than a maximum value of the first forcing function.

  • Patent number: 7242643
    Abstract: In an optical disk apparatus, after chucking an optical disk, the optical disk apparatus defers the start of the rotation of the optical disk, and measures the focusing drive voltage at two points, i.e., a point near a center of the optical disk and a point near an outer edge of the optical disk. Then, based on the measured values, the optical disk apparatus determine the angle at which the optical disk is slanted. Therefore, when the optical disk has been chucked inappropriately, the chucking state can be determined without rotating the optical disk, and scratching of the optical disk and damage to the optical disk apparatus can be prevented.

  • Patent number: 7212471
    Abstract: A method is for simultaneously operating the tray of an optical disk system and the front panel of the computer cabinet wherein the optical disk system is housed. In the method, the tray of the optical disk system is ejected immediately after the front panel of the computer case is completely opened when a tray operation instruction is issued and the front panel is currently at a close state. Additionally, the tray is retracted into the optical disk system before the front panel of the computer case is closed when a tray operation instruction is issued again and the front panel is currently at an open state so that the optical disk system may been closed inside a computer cabinet of the computer including HI-FI stereo. In the embodiment, the tray operation instruction is delivered via an output pin of the computer including HI-FI stereo and one of the reserved output pin of the optical disk system.

  • Patent number: 7206261
    Abstract: A loading mechanism includes a frame and a tray on which an information recording medium is placeable. The tray includes a groove part and is movable between a first position where the information recording medium is contained completely inside the frame and a second position where the information recording medium is exposed completely outside the frame. The loading mechanism further includes at least three projections arranged on the frame at predetermined intervals along the sliding directions of the tray. The projections include first and second guide and support parts forming the first and second ends of the arrangement of the projections. The first and second guide and support parts come into substantially point or linear contact with the groove part of the tray so as to guide and support the tray when the tray is in the second position.
