Abstract: Media data playback positioning method, such as audio data positioning, comprising a processor retrieving audio data from a memory, using a timer to time an extendable digit receiving period, receiving digits, generating a time value upon expiration of the extendable digit receiving period, and performing a playback operation on the media data based on the time value.

Abstract: A device for storing optical discs is disclosed. The device includes a housing, a carousel arranged in the housing for movement relative to the housing, the carousel having a plurality of storage compartments each for storing a disc, an opening in the housing through which a disc can pass, drive means for driving the carousel relative to the housing to align each of the storage compartments and a disc stored in that storage compartment in registry with the opening, and an ejection system to eject a disc from a storage compartment and through the opening in said housing. The ejection system is powered by a motor and a clutch system, and control means is provided to cause said carousel to rotate and to cause the ejection system to operate as instructed by a user.

Abstract: An optical disc access control and storage apparatus containing a rotating plate for storing discs thereon and rotating the same, a first disc-pushing mechanism for moving a disc along its radial direction from the rotating plate to a second disc-pushing mechanism wherein the second disc-pushing mechanism has a positioning slot for positioning the disc, an auxiliary-fixing mechanism for fixing the disc positioned in the positioning slot, a seizing mechanism for seizing the disc, a rotating mechanism fixed to the seizing mechanism for rotating the seizing mechanism, a coordinate-displacing mechanism connected to the rotating mechanism for controlling the horizontal and vertical positions of the seizing mechanism and at least one disc player for receiving the disc released from the seizing mechanism.

Abstract: A recording and/or playback apparatus of a dislike recording medium, such as optical disk, is equipped with a receiving portion, a recording and/or playback portion, an ejecting operation mechanism, a loading mechanism, and a positioning mechanism. In the receiving portion, a plurality of supporting portions supporting respective peripheral ends of a plurality of disklike recording media are formed in an annular form, and an opening portion is formed on the supporting portion. The recording and/or playback portion conducts recording and/or playback of the disklike recording media. The ejecting operation mechanism penetrates from the opening portion of the receiving portion and ejects a desired disklike recording medium out of the disklike recording media, from the supporting portion.

Abstract: A compact disk drive unit capable of changing disks in a very short time. An access mechanism is provided for transferring a disk between a rack and a plurality of disk driving mechanisms, wherein the access mechanism is pivotally supported by a central shaft which is approximately parallel with a central shaft of the rack. A disk transfer means is provided to selectively face the rack and the disk driving mechanisms to transfer a disk between them. The disk driving mechanisms are radially disposed around the central shaft of the access mechanism to face the revolving access mechanism at a preset distance.
