Abstract
An optical information recording/reproducing apparatus for use in an optical card, in which a moving speed of the optical card is detected on the basis of an information signal read out from the optical card and in which the information signal is corrected with the aid of the thus detected moving speed. Therefore, the data recorded on the optical card can be read out in a stable manner even when the optical card is transferred with a variation of its moving speed; and such apparatus can be manufactured at a low cost.
