Abstract
A method according to one embodiment includes instructing a drive to detect a written signal burst on a magnetic tape and stop movement of the tape in response to detecting the written signal burst. A search for a defect is conducted in a location proximate to the written signal burst. An apparatus according to one embodiment includes a plurality of detector structures positioned in an array. Each of the detector structures includes a pair of conductive layers separated by an insulating material. A write transducer is aligned with each of the detector structures. A controller is configured to cause one of the write transducers to write a signal burst in response to the associated detector structure encountering a defect.
Claims19
A method, comprising:
- instructing a drive to detect a written signal burst on a magnetic tape and stop movement of the tape in response to detecting the written signal burst;
- and
- searching a surface of the tape proximate to the written signal burst for a defect.
A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a tape drive to cause the tape drive to:
- move, by the tape drive, a magnetic tape to an approximate location of a defect based on linear position information previously stored in response to detecting the defect;
- detect, by the tape drive, a written signal burst on the magnetic tape;
- and
- stop, by the tape drive, movement of the tape in response to detecting the written signal burst.
An apparatus, comprising:
- a plurality of detector structures positioned in an array, wherein each of the detector structures include a pair of conductive layers separated by an insulating material;
- and
- a write transducer aligned with each of the detector structures;
- and
- a controller configured to cause one of the write transducers to write a signal burst in response to the associated detector structure encountering a defect.
