ABSTRACT:
A recording/reproducing apparatus disclosed herein uses a disk-type storage medium which has a spiral track divided into a plurality of continuous logical tracks. Each logical track extends at an angle less than 360.degree.. A head executes a track jump for retracing a desired logical track during tracing a logical track next to the desired track. Thus, no specific retrace area is necessary to be provided on the storage medium.
