In an optical information recording medium of the type wherein information is recorded or reproduced when a light beam scans each of a plurality of mutually parallel tracking tracks, an auxiliary track is extended between the adjacent tracking tracks and has at least one portion in parallel with the tracking tracks. In a method of recording or reproducing information by scanning a light beam on each of a plurality of mutually parallel tracking tracks on the recording medium, the recording medium has an auxiliary track which is extended between the adjacent tracking tracks and which has at least one portion in parallel with the tracking tracks and the light beam is kicked in the parallel portion of the auxiliary track.

An interpolation device arranged to input (a) a serial data sequence including a number of sampling data and (b) a serial flag sequence including flag data indicative of the validities of the number of sampling data, and arranged to output an output data sequence by replacing a part of the number of sampling data with interpolation data, includes a first juxtaposing circuit for receiving the input data sequence and the output data sequence and for outputting in parallel objective sampling data to be interpolated and a plurality of sampling data having a high correlation with the objective sampling data. An interpolation circuit is provided for outputting the output data sequence by selectively using the objective sampling data and the plurality of sampling data which are output from the first juxtaposing circuit. A second juxtaposing circuit is provided for receiving the flag sequence and for outputting in parallel a plurality of flag data indicative of validities of a part of the plurality of sampling data. A control circuit is provided for receiving the plurality of flag data which are output from the second juxtaposing circuit and for outputting control data to control the interpolation circuit. Finally, a switching circuit is provided for switching an output characteristic of the control circuit.

An information reproducing system is disclosed. This system is arranged such that information is read out from a recording medium having different types of first and second items of information and is output in the form of a signal. The waveform of the output signal is shaped and supplied as a reproduced signal. In the above-mentioned signal processing, this information reproducing system is adapted to control the shaping of the signal waveform in accordance with each type of information to be read out from the recording medium.

An information reproducing medium comprises plural tracks for recording information arranged to form a band and such plural bands are arranged normal to the direction of the track arrangement. The track has no area for obtaining an information reproducing clock. In a reproducing method, when information on one track of one band is to be reproduced, an information reproducing clock is derived from at least a portion of information on a track other than the one track, preferably a track adjacent thereto.

An information memory apparatus includes: an endless belt which is driven forward and in reverse by a motor and reciprocates a recording medium such as an optical card; an optical head for reading out information from the recording medium which is being moved by the endless belt; a memory for temporarily storing the information read out by the optical head; a transfer apparatus for transferring the information read out of the memory to the outside; and a control circuit for changing the positions at which the information stored in the memory is read in accordance with the reading of the information upon the forward and returning operation of the recording medium. The control circuit also changes the reading directions of the information from the memory in accordance with the forward and returning operations of the recording medium. With this apparatus, the information reading efficiency is improved and the information is efficiently transferred by a simple constitution, while reducing the number of memories.

An information recording/reproducing apparatus uses a card-like recording medium having an area for information recording and a blank area, the area for information recording having a reflectivity different from that of the blank area. The apparatus includes a head unit for performing at least one of recording and reproduction, an autotracking servo, a stepping motor and the like cooperating to cause the card to reciprocate relative to the head unit, and an abnormal state detect circuit for detecting whether the card is inserted in the apparatus in a normal state. The abnormal state detect circuit includes a photosensing unit consisting of a light-emitting element for emitting light rays onto the card and a light-receiving element for receiving the light rays from the card. The photosensing unit is deviated with respect to a central portion of the card along a direction perpendicular to a reciprocal movement of the card so that the area for information recording is irradiated with the light rays from the light-emitting element upon insertion of the card in the normal state.
