ABSTRACT:
A device for processing data recorded on a tape medium includes a first control part that controls a read head to read specific data recorded in a first area among data recorded in a first format on the tape medium. Data in the first format is recorded at a first recording density. The device further includes a second control part that controls a write head to write the specific data in a second area different from the first area of the tape medium and to write the specific data in a second format in a third area different from the second area of the tape medium. Data in the second format is recorded at a second recording density different from the first recording density. Moreover, the device may include a recording part for recording specific information that specifies a read position of other data among data recorded in the first format on the tape medium.
