Optical card recording and reproducing device

摘要

An optical card recording and reproducing device including an optical head for emitting a light beam spot to the optical card having a plurality of parallel data tracks to which data is recorded; a transfer system for transferring the optical card and/or the optical head; and a track number confirmation means for confirming the track number recorded in the address data area in the data track of the optical card. The optical card recording and reproducing device also includes a transfer stopping means for stopping the optical head when an incorrect track number is deleted. The system minimizes the relative transfer distance between the optical card and the optical head, and at the same time, the total relative transfer distance of the optical card and/or the optical head when confirming the track number more than twice. Thus, the total time required for track number confirmation can be greatly shortened.
