ABSTRACT:
A data copying method comprises the steps of checking a starting track address and an end track address which are used for controlling a copying of a data from each set of several recorded tracks in a master disk to a slave disk having several unrecorded tracks only so as to store the starting track address and the end track address for each of the recorded tracks, reproducing the data from each of the recorded tracks in the master disk repeatedly for each recorded track to supply a reproduced data signal from the data, and recording and reproducing data signal onto the slave disk at its track addresses corresponding to those addresses of the recorded tracks in the master disk repeatedly for each recorded track in the master disk storage medium, the recording of the reproduced data onto the slave disk being stopped at track addresses of the slave disk corresponding to those addresses of the unrecorded tracks in the master disk.
