Pre-recorded optical reflective videodisk system "Laser vision" 50 Hz/625 lines - PAL

Applies to pre-recorded optical reflective videodisks compatible with 50 Hz-625 lines CCIR monochrome and colour coding PAL systems, and defines those parameters that effect the interchangeability of the disk, excluding limitations of the programming material and source. Serves as a reference for manufacturers intending to make disks or players compatible with the optical system described. See also IEC 61106.

FOREWORD
1)
The formal decisions or agreements of the I E C on technical matters, prepared by Technical Committees on which all
the National Committees having a special interest therein are represented, express, as nearly as possible, an international
consensus of opinion on the subjects dealt with.
2)
They have the form of recommendations for international use and they are accepted by the National Committees in that
sense.
3)
In order to promote international unification, the I E C expresses the wish that all National Committees should adopt
the text of the I E C recommendation for their national rules in so far as national conditions will permit. Any divergence
between the I E C recommendation and the corresponding national rules should, as far as possible, be clearly indicated
in the latter.
PREFACE
