In order to play back these two types of videodisks it is necessary to use an optical pick-up device for the
13、optical system and a capacitance pick-up device for the capacitance system. These videodisks are characterized by mechanical, electrical and optical parameters for which measuring methods are unknown.

14、RAMETERS 1 Scope This International Standard collects the different typical parameters for videodisks described in IEC 844,845,856 and 857 and proposes a method of measurement for each. Some of these parameters can be measured by well known methods existing in every labo- ratory, whilst other parame
15、ters need specific equipment described in the annexes. 2 Normatlve references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard.
