A tape apparatus includes a tape drive and a processor. The tape drive is configured to perform data reading and data writing on a magnetic tape in which a plurality of tracks are formed. The processor is configured to control the tape drive to perform data reading and data writing on the plurality of tracks in a first segment among a plurality of segments obtained by dividing the magnetic tape in a running direction. The processor is configured to reserve a first track of the plurality of tracks as a copy target upon determining that an abnormality occurs in the first segment on the first track. The processor is configured to instruct the tape drive to copy data recorded in the first segment on the first track to a second segment on the first track at a predetermined timing. The second segment is adjacent to the first segment.

Tape apparatus and control device

In an erasing and recovering system for a data block on a magnetic tape in a magnetic tape recording and reproducing apparatus, the system includes: a detecting unit for detecting data error caused by a damaged portion on the magnetic tape by reading a data block just after the data block is written to the magnetic tape; a calculating unit for calculating the circumference of the magnetic tape including the damaged portion; an erasing unit for erasing half of the circumference including the damaged portion; and a data write unit for re-writing the same data block as the data block including the error into another half of the same circumference as the circumference including the damaged portion.
