Abstract
In one embodiment, a drive-implemented method includes determining, by a tape drive, that a magnetic recording tape is compatible with a first format, the tape drive having an array of transducers including an inner transducer and subarrays of the transducers positioned on opposite sides of the inner transducer, reading from or writing to the magnetic recording tape, by the tape drive, using the array of transducers in a first mode of operation corresponding to the first format, and processing data, by the tape drive, using only the transducers in the subarrays in the first mode of operation.
Claims11
A drive-implemented method, comprising:
- determining, by a tape drive, that a magnetic recording tape is compatible with a first format, the tape drive having an array of transducers including an inner transducer and subarrays of the transducers positioned on opposite sides of the inner transducer;
- reading from or writing to the magnetic recording tape, by the tape drive, using the array of transducers in a first mode of operation corresponding to the first format;
- and
- processing data, by the tape drive, using only the transducers in the subarrays in the first mode of operation.
A computer program product for writing and/or reading a first format and a second format in an apparatus, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause a tape drive to:
- determine, by the tape drive, that a magnetic recording tape is compatible with the first format, the tape drive having an array of transducers including an inner transducer and subarrays of the transducers positioned on opposite sides of the inner transducer;
- read from or write to the magnetic recording tape, by the tape drive, using the array of transducers in a first mode of operation corresponding to the first format;
- and
- process data, by the tape drive, using only the transducers in the subarrays in the first mode of operation.
A drive-implemented method, comprising

- reading from or writing to the magnetic recording tape, by the tape drive, using the array of transducers in a first mode of operation corresponding to the first format;
- processing data, by the tape drive, using only the transducers in the subarrays in the first mode of operation;
- and
- processing data, by the tape drive, using at least a portion of the transducers in each of the subarrays and the inner transducer in a second mode of operation.
