Title: Information recording medium
Inventor: SUZUKI KENICHI
IPC: G11B23/00
Filed: 1986-07-03
Abstract: PURPOSE:To assure the straightforwardness of the medium, and to attain the accurate recording and reproduction of information by providing a projection projected in the same plane as the medium at both ends on the side along the moving direction of an information recording card. CONSTITUTION:In moving between a frame 14 and a plate spring 16, the optical card 1 receives a moment in the direction M by a friction force of the spring 16 and the driving force of a guide roller 18a and the straightforwardness is hindered. In a burr or flaw exists at the side of the card 1, the meandering state is caused frequently and excellent information recording/reproduction is disabled. In providing projections 4a, 4b at both ends of the side along the moving direction of the card 1, even in the presence of burr or flaw, it does not bring into contact with the guide face and the similar action to the projection near the center at the side hindering the straightforwardness is excluded. Thus, the accurate recording/reproduction is attained to a pit string of information.
