Abstract

An array of scanning photodiodes onto which is projected, by appropriate optical means, the image of a segment of length corresponding to the recording track, this track being illuminated by an appropriate light source. The speed of the scanning wave of the photodiode array at the level of the support is equal to that of the support speed and in the same sense as the latter speed. Return to the origin at the end of each sweep cuts the recording into a certain number of segments of arbitrary length corresponding to the magnification, near to the optical system, of the array length, and is chosen as a function of the dynamic performances required.
