Optical card recording/reproducing apparatus wherein a data process is made during an access operation.

摘要

A recording/reproducing apparatus for recording/reproducing data by relatively moving either of an optical card (1) and optical head (12) wherein, in order that data may be recorded/reproduced on the optical card (1) by moving either of the optical head (12) and optical card (1), during an access operation to gain access to reach a target track, such data process as adding data for detecting and correcting errors to data to be recorded in the optical card (1) by a data encoding circuit (20) or correcting errors on data already read out by an error correcting circuit (18) is made in parallel. The data are also transferred during the access operation. <IMAGE>
