Patent number: 5380996Abstract: An optical card recording/regenerating apparatus performs at least either recording or regenerating while reciprocating an optical card with respect to an optical head. At this time, the apparatus drives the optical card so that the relative speed between the optical card and optical head will be constant over a data division of the optical card and part of ID divisions in the vicinities of both edges thereof. When the relative speed becomes constant, the apparatus performs at least either recording or regenerating. The apparatus offers a smaller drive length. This realizes downsizing of an optical recording/regenerating apparatus and reduction of an access time.Type: GrantFiled: July 7, 1993Date of Patent: January 10, 1995Assignee: Olympus Optical Co., Ltd.Inventor: Toshio Horiguchi

Patent number: 5285433Abstract: In an apparatus for recording and/or reproducing data on and/or from an optical card having a plurality of tracks, each of which includes a data portion and ID portions provided at both ends of the data portion, in said data portion the data is recorded in a plurality of sectors in a reciprocal manner by projecting from an optical head a recording or reproducing light beam onto the optical card, while the optical card is moved with respect to the light beam, a relative position of the optical card with respect to the optical head is detected to derive a sector position signal. A start point of a sector for which the data will be recorded or reproduced is determined by counting the sector position signal. The sector position signal is derived by counting pulses generated by a rotary encoder coupled with the motor for moving the optical card to derive a count value and a comparator for comparing the count value with a reference value which is generated in accordance with a predetermined track format.Type: GrantFiled: August 5, 1991Date of Patent: February 8, 1994Assignee: Olympus Optical Co., Ltd.Inventors: Mitsuo Oshiba, Toshio Horiguchi
