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.

An apparatus according to an embodiment includes an array of transducers including an inner transducer and subarrays of the transducers positioned on opposite sides of the inner transducer, and a controller coupled to the transducers. The controller is configured to process data using only the transducers in the subarrays in a first mode of operation. Moreover, the controller is configured to process data using only a portion of the transducers in each of the subarrays in a second mode of operation, where the inner transducer is inactive in the second mode of operation.

The first format specifies locations of data and a contiguous spare area on the tape and compatibility with a second format. The second format specifies a set of second active channels different than a set of first active channels specified by the first format.

An apparatus according to one embodiment includes an array of 2N+1 transducers and a controller directly electrically coupled to each of the transducers, where the controller is configured to use transducers on only one side of a centerline of the array in a first mode of operation.
