  • Patent number: 9324359
    Abstract: Data recording and reproduction systems, apparatus, and methods provide efficient recording of and reproduction from storage media having multiple surfaces. In particular, a grouping processing unit groups data based on several factors. The grouped data can then be efficiently stored on storage media having multiple sides to increase the efficiency of storage and retrieval of such data. For example, data belonging to the same group is not stored on two surfaces of the same storage media to avoid having to remove and reverse the direction of the storage media in order to store data on or retrieve data from the other side of the storage media.

  • Patent number: 7031231
    Abstract: A disk holder springing-out prevention device is constituted by utilizing an existing loading block LB. A disk holder 3 is restricted to an accommodated position within a magazine M by means of a stopper 1a provided on a holder guide rail 1. In general, the initial position of the loading block LB is adapted to be a raised/lowered position corresponding to the uppermost disk holder 3 and the stopper 1a is adapted to be superimposed in the vertical direction with an engagement projection 2a of a holder extracting member 2 when the holder extracting member 2 is in the initial position in the feed direction. In this way, positional restriction of the uppermost disk holder 3 is effected by the holder extracting member 2 whereas the stopper 1a performs positional restriction of the remaining disk holders 3. As a result, springing out of the disk holders 3 from the magazine M can be reliably prevented.

  • Patent number: 6990674
    Abstract: A CD or DVD disc processor, as shown, a recorder or duplicator (it could be a printer) has a pivoting picker mechanism having only one degree of freedom when driven for handling the discs for recording and stacking recorded discs. The picker mechanism picks the disc from the top of a supply stack of blank discs and places the disc on a loading tray of a recorder. The disc is moved into the recorder drive and removed after recording. The picker mechanism then picks the disc from the tray apparatus, the tray is retracted into the recorder, and the picker mechanism pivots beyond the tray to deposit the completed discs on a completed stack storage space below the tray level.

  • Patent number: 6963519
    Abstract: A disc device comprising a transfer unit operable to provide a transferring force to a disc inserted from the outside to transfer the disc into a storage area in the device, a sensor unit for detecting the position of the inserted disc, and a control unit for controlling a operational speed of the transfer unit. The control unit controls the operational speed of the transfer unit in the disc loading direction at a low-speed until the disc inserted from the outside reaches the transfer unit. The control unit then adjusts the operational speed of the transfer unit in the disc loading direction from a low-speed to a high-speed when the sensor unit detects that the disc is inserted into the position in which a transferring force from the transfer unit is given to the disc, or after a predetermined period of time has elapsed. Accordingly, the disc device reduces operation noise and resistance when the disc is inserted.

  • Patent number: 6947357
    Abstract: A changer-type disk device includes a disk storage section holding disks arranged in the axial direction of the disks; a drive unit for reproducing and/or recording information from/in a disk selected from the disks in the disk storage section; a drive activating mechanism for moving the drive unit back and forth between a drive position where the selected disk is driven and a retracted position where no disk is driven; and pressing members. The pressing members come into pressure contact with the circumferential edges of the waiting disks held in the disk storage section to push them toward the disk storage section from the outside in the radial direction, and are separated therefrom when the drive unit is moved from the drive position to the retracted position. Accordingly, the waiting disks can be locked in the radial direction; thus, a rattle noise occurring from the waiting disks during driving of the selected disk can be reduced.
