The potential applications for CD technology represent numerous<br />

attractive markets. They could all gain widespread use by the consumer, in<br />

part because of the enthusiastic acceptance of CD players.<br />

DATAQUEST ANALYSIS<br />

Digital audio disks offer better sound than conventional records and<br />

tapes and put an end to noise and signal degradation over time. This is<br />

because a laser pickup eliminates direct contact with the disk surface;<br />

hence, disk wear is avoided. Using error-detection and -correction circuitry<br />

together with software, the conventional analog filtering techniques are<br />

eliminated. This provides audio that is free of noise and that has concert<br />

hall dynamic range. Digital audio tapes (DAT) and DAT players also offer<br />

perfect sound reproduction with virtually no deterioration regardless of the<br />

number of times the tape is played.<br />

The supply of integrated circuits to CD or DAT player manufacturers is a<br />

significant market opportunity for semiconductor manufacturers in the late<br />

1980s and early 1990s. Dataquest believes that as prices for players, CDs,<br />

and DATs come down, and as older music systems wear out, owners will replace<br />

their combination LP/cassette music libraries with CDs and DATs.<br />
