Provided is a magnetic tape device including: a magnetic head having a magnetic element that acts in proximity to a magnetic layer formed on a front surface of a magnetic tape; and a support member which is disposed at a position facing the magnetic head and against which a back surface of the magnetic tape provided on a side opposite to the front surface is pressed, in which the support member has a groove formed along a running direction of the magnetic tape only in a region corresponding to a non-acting region except for a region of the magnetic layer on which the magnetic element acts.

A storage device configured to store data on a tape is provided. In one aspect, the storage device includes the tape, which is configured to store data, and a data head, which is configured to read and/or write data from and/or to the tape. The storage device further includes an actuator configured to move the tape in a length direction in a step-wise manner. The actuator can include a plurality of pulling electrodes, wherein each pulling electrode can be activated to exert a pulling force on the tape, and a plurality of clamping electrodes, wherein each clamping electrode can be activated to clamp the tape.

An apparatus, according to one embodiment, includes a module having an array of transducers, and a thermoelectric cooling element positioned proximate to the array of transducers. An apparatus, according to one embodiment, includes a module having an array of transducers, a thermoelectric cooling element positioned proximate to the array of transducers, and a heating element positioned proximate to the array of transducers. A method of maintaining a span of an array of transducers of module to a specification, according to one embodiment, includes determining whether the span of the array of transducers in a module is different than a target based on a specification. In response to determining the span is greater than the target, a control signal is applied to a thermoelectric cooling element positioned proximate to the span of the array of transducers for contracting the span of the array of transducers toward the target.

A storage system can include a first tape storage drive (TSD), a second TSD, and a printed circuit board assembly (PCBA) where the first and second TSD are coupled back-to-back, with the PCBA between the two.

Aspects of the present disclosure relate to rewinding a tape medium. Data is written to the tape medium under a first tension. An end data region of the tape medium is identified, where the end data region is not the end of the tape medium. An indication that the tape medium is to be unmounted is received. The position of the tape medium is moved to the end data region. The tape medium is then rewound from the end data region under a second tension, the second tension being lower than the first tension.
