Iii. CD-R & CD-RW Audio Discs

The CD-77 can play CD-R & CD-RW audio discs that have been recorded on a computer or CD-recorder. The quality of CD-R & CD-RW audio discs varies widely which may affect playability.

iv. Handling Compact Disks

Always handle Compact Discs with care. The playback of a disc will not be impaired by small dust particles, a few light fingerprints, or slight scratches. But large scratches, or a thick layer of oily fingerprints, can prevent the CD-77 from tracking the disc properly.

Incidentally, although the tracking optical pickup “plays” the disc through its clear side, the actual data surface is embedded directly beneath the label, protected only by a very thin coating of lacquer. So a scratch that cuts through the label may damage the disc more than a similar scratch on the transparent ‘playing’ surface. Thus you should treat both surfaces of the disc with care.

Severe scratches or fingerprints may cause the CD-77 to miss-track (skipping ahead, or repeating the same passage). Less severe damage may produce very brief bursts of high-frequency noise. The tracking and error- correction circuits of this compact disc processor player are unusually sophisticated, providing secure tracking of flawed discs that are unplayable on some other players. Nevertheless, the discs should not be abused or handled carelessly. For best results, grasp the disc only by its edges.
