Title: Card type optical recording medium
Inventor: TAMURA TOMOYUKI
IPC: G11B7/00
Filed: 1993-12-13
Abstract: PURPOSE:To prevent the occurrence of the relative positioning error of an optical card and to perform stable recording/reproducing in a high or low temperature environment by providing a reverse mark on the optical card side instead of a shielding plate. CONSTITUTION:A reflection type reverse mark reading head (a light source and a sensor) 41 is fixed by a mark reading head fixing shaft 46 so as to intersect on the reverse mark 4 when the optical card 1 is moved in direction A in a reproducing device. The head 41 is arranged in the same line as an optical head 51 (moved in direction C on a shaft 53 by a motor 52) for performing the recording/reproducing of a card. By moving the card in the direction of arrow A, reflected light is read on the mark 4 and a pulse signal is generated, thereby detecting a reverse position. Since the reverse mark and the card are simultaneously expanded and contracted, deviation is not caused between recording/ reproducing starting and finishing positions, and the stable recording/ reproducing is performed.
