According to one aspect, an exemplary multi-format magneto resistive recording head is provided. The magnetic head includes a first set of data transducers configured transversely across a direction of tape transport, the first set of data transducers associated with a first data format, and a second set of data transducers configured transversely across the direction of tape transport, the second set of data transducers associated with a second data format, wherein the first set of data transducers and the second set of data transducers are separated by a distance along the direction of tape transport. In one example, the magnetic head includes a first raised elongated island positioned transversely across the direction of tape transport, the first island including the first set of data transducers, and a second raised elongated island positioned transversely across the direction of tape transport, the second island including the second set of data transducers.

Multi-format thinfilm head and associated methods

A thinfilm magnetic head for tape drives that enables onsite, real time temperature monitoring of the head-media interface. The head includes a media interface contacting a data bearing surface of the tape. A thinfilm, read-write element and a thinfilm sensor of a thermosensor are positioned on the head-media interface. The thermosensor generates a signal based on the temperature of the media interface. The media interface includes an active island and an optional inactive island positioned transverse to the tape travel path with the read-write element in the active island. The sensor may be placed on the inactive island or on the active island adjacent the read-write element. In one embodiment, a plurality of read-write elements and thermosensors are provided and sensors of the thermosensors are positioned on the inactive island and/or the active island among or between the read-write elements or adjacent an end element.

Magnetic tape head with thinfilm thermosensors for head-media interface temperature monitoring

A head for a tape drive system has a plurality of transducers formed on a substrate and protected by a cover bar, with a tie bar bonded to the cover bar. The tie bar extends along a tape-facing surface beyond the cover bar, enhancing the structural integrity of the head. Wear bars may be bonded to the substrate, cover bar and tie bar. Alternatively, the tie bar may have a notch within which the substrate and cover bar are bonded. The tie bar reduces misalignment and instability of the transducers, providing increased storage capacity and greater reliability and durability of the tape drive system.
