The CD language unit 100 according to the present invention has a good sound quality because the CD language 100 reads directly from a CD and repeatedly plays the content, which is reproduced at interval repetition. The CD operation for this is as follows.

Normally, a compact disc (CD) which is a recording medium is rotatably mounted on a spindle motor (not shown). Pick-up mechanism 116 is located below the bottom surface of the disk and transmits a laser beam to the disk for receiving data and receives the beam reflected therefrom, mounted on a slider motor that can be shifted in the radial direction of the disk. The motor drive 114 controls the spindle motor and the slider motor to rotate the track of the disc at a constant linear velocity with respect to the pickup head.

The signal processor 108 controls the position of the pickup head 116 while processing the signal output by the pickup head 116 and allows the data read from the disc to be read. For position control, a closed loop control system comprising a servo circuit and a motor drive synchronously drives the spindle motor and the slider motor in response to an output signal from the pickup head 116. This allows access to a predetermined position on the disc by the pickup head 116. The pickup head 116 is supported by a double-axis device that can be shifted slightly, thereby enabling focus correction and tracking correction.

In addition, in the CD, data is helically recorded on the disk surface at the same density and proceeds helically from the center. As shown in FIG. 3, the data area is divided into a lead-in area, a program area, and a lead-out area.

The program area, which is substantially user data, is positioned between the lead-in area and the lead-out area so that one session is formed. A maximum of 99 tracks can be stored in the program area, where one track corresponds to one part of the music and the number of tracks of the disc dedicated to the music corresponds to the number of music parts. One track can be further divided into frames. The frame is the minimum unit for data processing and consists of 24 bytes. A group of 98 sequential frames (2352 bytes long) is called a sector.

Various control information such as attribute information and the beginning of the track are recorded in the lead-in area and the lead-out area. As shown in FIG. 4, a so-called TOC (table of contents), which is a table for managing attribute information and control information on a disc in track units, is stored in the lead-in area. In the TOC, one record consisting of 96 bits of so-called "Q channels" is prepared for each track, and the Q channels are stored in track order in the program area. The data structure of the Q channel conforms to the field structure (so-called "Q format"), and the data for the track is stored in the corresponding field. The values stored in the individual fields (control, ADR) in the Q channel are used during track search on the CD or when data in the track is read. The PSec field is used to indicate the disc type.
