Abstract

Abstract An apparatus for recording/reproducing information on/from an optical card, in which a card identifying information data, which is recorded on the outside of a normal data recording portion of an optical card, can be reproduced by an optical head, a demodulating circuit and a focusing/tracking circuit, which are originally provided for recording/reproducing information on/from the normal data recording portion of the optical card. Therefore, in the apparatus according to the invention, it is unnecessary to specially provide the other apparatus for reproducing the card identifying information data, so that the apparatus as a whole can be made small and the cost therefor can be decreased.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 196 words
An apparatus for recording and reproducing information data on and from an optical card including an information data recording area and a card identifying information recording area formed outside said information data recording area, comprising: support means for receiving and supporting said optical card when said optical card is inserted in said apparatus; optical means for emitting light beams to perform at least one of recording information data on and reproducing information data from said information data recording area of said optical card; driving means for causing relative movement between said optical card and said light beams in a track direction; and controlling means for controlling said optical means and said driving means to cause said optical means to be in a position outside said information data recording area of said optical card to reproduce said card identifying information recorded on the card identifying information recording area when said optical card is supported on said support means, wherein said information data recording area comprises a plurality of information data recording tracks each including a guide means for light beams illuminated thereon and said card identifying information recording area includes no guide means for said light beams.
Claim 2
Independent Claim 196 words
An apparatus for recording and reproducing information data on and from an optical card including an information data recording area and a card identifying information recording area formed outside said information data recording area, comprising: support means for receiving and supporting said optical card when said optical card is inserted in said apparatus; optical means for emitting light beams to perform at least one of recording information data on and reproducing information data from said information data recording area of said optical card; driving means for causing relative movement between said optical card and said light beams in a track direction; and controlling means for controlling said optical means and said driving means to cause said optical means to be in a position outside said information data recording area of said optical card to reproduce said card identifying information recorded on the card identifying information recording area when said optical card is supported on said support means, wherein said information data recording area comprises a plurality of information data recording tracks each including a guide means for light beams illuminated thereon and said card identifying information recording area includes no guide means for said light beams.
Claim 3
Dependent Claim 204 words
An optical card system, comprising: an optical card including an information data recording area and a card identifying information recording area formed outside said information data recording area, wherein said information data recording area comprises a plurality of information data recording tracks each including a guide means for light beams illuminated thereon and said card identifying information recording area includes no guide means for said light means; an apparatus for recording and reproducing information data on and from said optical card, comprising: support means for receiving and supporting said optical card when said optical card is mounted in said apparatus; optical means for emitting light beams to perform at least one of recording information data on and reproducing information data from said information data recording area of said optical card; driving means for causing relative movement between said optical card and said light beams in a track direction; and controlling means for controlling said optical means and said driving means to cause said optical means to be in a position outside said information data recording area of said optical card to reproduce said card identifying information recorded on the card identifying information recording area when said optical card is supported on said support means.
Claim 4
Dependent Claim 204 words
An optical card system, comprising: an optical card including an information data recording area and a card identifying information recording area formed outside said information data recording area, wherein said information data recording area comprises a plurality of information data recording tracks each including a guide means for light beams illuminated thereon and said card identifying information recording area includes no guide means for said light means; an apparatus for recording and reproducing information data on and from said optical card, comprising: support means for receiving and supporting said optical card when said optical card is mounted in said apparatus; optical means for emitting light beams to perform at least one of recording information data on and reproducing information data from said information data recording area of said optical card; driving means for causing relative movement between said optical card and said light beams in a track direction; and controlling means for controlling said optical means and said driving means to cause said optical means to be in a position outside said information data recording area of said optical card to reproduce said card identifying information recorded on the card identifying information recording area when said optical card is supported on said support means.
