A stocker box stocking a plurality of CDs and a player box adjacent to the stocker box are disposed next to each other. Each of the boxes has an opening on a side wall so as to oppose to an opening formed on a side wall of the adjacent box. A horizontal guide rail device is provided in each box, extending to the opening thereof. A horizontal carrier is provided to be moved along the guide rail devices of the stocker and second player boxes passing through the openings. A plurality of coils are mounted on each of the guide rail devices, arranged in a moving direction of the horizontal carrier. The horizontal carrier has a magnet to form a magnetic field passing through some of the coils. The coils are sequentially excited so as to move the carrier in the moving direction.

Carrier system for carrying mediums

A storing portion is provided for storing a plurality of recordable discs, and a recording device is for recording an accompaniment reproduced by a singalong disc player and a vocal part sang at the accompaniment. A loading device is provided for carrying a disc between the storing portion, and the recording device. An ejecting mechanism is provided for ejecting a recorded disc.

Recording system for signalong disc player

A recording device is provided for recording an accompaniment reproduced by a singalong disc player and a vocal part sang at the accompaniment on a recordable disc. A rerecording command during recording is detected for rerecording information on the recordable disc and for producing a rerecording signal. In response to the rerecording signal the recording the information is stopped, and an address of a recorded area of the disc is stored in a memory as an unnecessary area. In response to a restart signal, recording the information is restarted from an end of the unnecessary area. When the rerecording has been finished, the recordable disc is finalized such that the unnecessary area is not reproduced thereafter based on the stored address.

Recording system for a singalong disc player

A disc playing and controlling apparatus which includes a plurality of magazine type disc players. When a first disc player is operating, the apparatus controls the other disk players to find and load a disc holding the next song to be played. Before searching for the next song, the controller determines whether one player is already set in a standby position or whether the next song is located in the player currently being operated. If no player has been set for the next program, the apparatus reads the next selection from a program list and identifies which magazine contains the selected program based on a data map. The map stores each player number and magazine number in an one-to-one relation with the table of contents data for each song.

Controlling playing operations of a plurality of magazine type disc

A disk storage/select player includes several disks and several menu boards for indexing data items contained on the disks. The menu boards are each shaped like a polyhedral column. A driver turns one of the menu boards, and a synchronous rotation transfer element transfer the rotation of the one menu board to the remaining menu boards so that all of the menu boards rotate in synchronism.

Disk storage/select player

A multi-disk player having a magazine for accommodating plural disks and a playback means. The playback means moves along an axis parallel to the axis of alignment of the disk in the magazine to a position adjacent a selected disk. The selected disk is extracted from the magazine and moved to a playback position in the playback means. Movement of the disk is under control of a motor, a movable member which responds to the motor and a tray engagement member which is actuated by the movable member. The movable member also actuates camming mechanisms which control the clamping and unclamping of the disk in the playback position and the unlocking and locking of the pick up means.
