35、 60908:1999 AUDIO RECORDING - COMPACT DISC DIGITAL AUDIO SYSTEM - 1 Scope and object This standard is applicable to a prerecorded optical reflective digital audio disc system. This standard defines those parameters of compact disc that affect interchangeability between discs and players. It is also
36、intended as a reference for manufacturers wishing to produce discs and/or players that conform to the system described in this standard. It deals with discs of 80 mm in diameter as well as those of 120 mm in diameter. 2 Normative references The following normative documents contain provisions which,
37、 through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possib
38、ility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies.

This side, the encoded side, is covered in turn by a reflective and a pro
44、tective layer. The information of the disc is stored in a spiral-shaped track consisting of successive shallow depressions (pits). When the disc is playing and viewed from the read-out side, the spiral starts near the centre of the disc and finishes near its edge. The lengths of the pits and the spa
45、ces between them can take discrete values only, and represent the encoded two-channel audio information. The information is read out by means of a beam of light which passes through the plain, .e. the non-encoded side of the transparent disc to the encoded side, where it is reflected and modulated b
46、y the recorded information (see figure 2b, detail E). The information is followed by means of a servo-system for tracking and focusing. 4 Requirements for measurements 4.1 Conditions of measurement Measurements and mechanical checks shall be carried out within the following limits unless otherwise s
