An apparatus, according to one embodiment, includes a magnetic head having servo readers of known pitch, a drive mechanism for passing a magnetic recording tape over the magnetic head, and a controller electrically coupled to the magnetic head. The controller is configured to measure, using signals from the magnetic head, a servo band difference at various locations along a length of the magnetic recording tape. The controller is also configured to cause storage of servo band difference information about the servo band difference measurements in association with the magnetic recording tape.

An editing apparatus for an editing video sequence that includes an editing unit for setting a first range to one part of the video sequence; a video sequence file generating unit for generating a video sequence file including video sequence corresponding to the first range and video sequence corresponding to a second range, within the second range is consecutively preceding to and/or subsequent to the first range; and an output for outputting the video sequence file.

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 computer-implemented method for measuring servo to servo reader spacing in a module, according to one embodiment, includes cause emission of a measurable electro-magnetic signal from two writer elements that are fixed at a same span as a nominal servo reader spacing. The writer elements are positioned in multiple relative positions along a transducer array of a module having servo readers in the transducer array. The strength of the electro-magnetic signal detected by each servo reader is measured at the multiple relative positions. A determination is made, from the measured strengths, whether the servo reader span matches the nominal servo reader spacing.

A media device may comprise a controller, a tape head, a tape comprising tape-position indicia, an indicia detection device, and an adjusting device. The indicia detection device may be configured to detect the tape-position indicia and provide an output corresponding to a tape position. The controller may be configured to send an adjustment command based on the output. The adjusting device may be configured to adjust the media device between a first configuration and a second configuration, based on the adjustment command. The tape may physically contact the tape head in the first configuration and not physically contact the tape head in the second configuration.

An apparatus configured to characterize a magnetic recording tape of a tape cartridge, according to one embodiment, includes a magnetic head having servo readers of known pitch, a drive mechanism for passing a magnetic recording tape over the magnetic head, and a controller electrically coupled to the magnetic head. The controller is configured to measure, using signals from the magnetic head, a servo band difference at various locations along a length of the magnetic recording tape of a tape cartridge. The controller is also configured to store the servo band difference measurements and/or derivatives thereof in association with the tape cartridge.

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.

A method for characterizing a magnetic recording tape of a tape cartridge, according to one approach, includes measuring, using a magnetic head having servo readers of known pitch, a servo band difference at various locations along a length of a magnetic recording tape of a tape cartridge. The servo band difference measurements and/or derivatives thereof are stored in association with the tape cartridge. This procedure creates a characterization of the magnetic recording tape that is useful for assessing aging of the magnetic recording tape, as well as improving subsequent reading and/or writing operations.
