Abstract
A magnetic tape control apparatus includes a control device that executes a process including: detecting an occurrence of speed fluctuations of a running magnetic tape for each recorded area from which a synchronization error is detected, when the synchronization error of a bit signal of a track is detected with a time lag between any of tracks of the running magnetic tape partitioned in units of recording areas; and setting the recording area as an unavailable area in accordance with a state where the speed fluctuations in the recording area occur.
Claims12
A magnetic tape control apparatus comprising:
- a control device that executes a process including:
- detecting an occurrence of speed fluctuations of a running magnetic tape for each recorded area from which a synchronization error is detected, when the synchronization error of a bit signal of a track is detected with a time lag between any of tracks of the running magnetic tape partitioned in units of recording areas;
- and
- setting the recording area as an unavailable area in accordance with a state where the speed fluctuations in the recording area occur.
A non-transitory computer-readable recording medium having stored therein a program for causing a computer to execute a control process comprising:
- detecting an occurrence of speed fluctuations of a running magnetic tape for each recorded area from which a synchronization error is detected, when the synchronization error of a bit signal of a track is detected with a time lag between any of tracks of the running magnetic tape partitioned in units of recording areas;
- and
- setting the recording area as an unavailable area in accordance with a state where the speed fluctuations in the recording area occur.
A method for controlling a magnetic tape, the method comprising:
- detecting an occurrence of speed fluctuations of a running magnetic tape for each recorded area from which a synchronization error is detected, when the synchronization error of a bit signal of a track is detected with a time lag between any of tracks of the running magnetic tape partitioned in units of recording areas;
- and
- setting the recording area as an unavailable area in accordance with a state where the speed fluctuations in the recording area occur.
