A plurality of gap patterns deviate from each other by a predetermined interval in a direction corresponding to a longitudinal direction of the magnetic tape, between the gap patterns adjacent to each other along the direction corresponding to the width direction of the magnetic tape. A substrate is inclined with respect to the first imaginary straight line.

A plurality of gap patterns are formed on a front surface of a substrate along a direction corresponding to a width direction of a magnetic tape.

The plurality of equalizers perform the waveform equalization by using a plurality of non-linear filters that have been learned to reduce distortion that occurs non-linearly in the plurality of playback signal sequence according to a condition under an environment in which the data is read from the magnetic tape. The plurality of non-linear filters being optimized to a suitable characteristic for the plurality of reading elements by optimization based on the plurality of reading results.

A cartridge is provided and includes tape-shaped magnetic recording medium; and cartridge memory; wherein cartridge memory includes communication unit that communicates with recording/reproducing device in state where cartridge is loaded on recording/reproducing device; storage unit; and control unit that stores, reads, and transmits information, wherein information includes manufacturing information of cartridge and adjustment information for adjusting a tension applied to the tape-shaped magnetic recording medium in a longitudinal direction of tape-shaped magnetic recording medium thereof, tape-shaped magnetic recording medium has a plurality of servo bands, and wherein a temperature expansion coefficient α of the tape-shaped magnetic recording medium satisfies 6 ppm/° C.≤α≤8 ppm/° C.

An apparatus, in accordance with one approach, includes a receiving area configured to receive a plurality of tape spool pairs. A drive mechanism is configured to selectively drive the tape spool pairs. A magnetic head configured to perform data operations on magnetic recording tapes of the tape spool pairs is also present. A positioning mechanism is configured to selectively align the magnetic head to a selected one of the tape spool pairs. An engagement mechanism is configured to create a relative movement between the magnetic head and the magnetic recording tape of the selected tape spool pair for engaging the magnetic recording tape with the magnetic head. A controller is configured to instruct the drive mechanism to drive the selected tape spool pair during performance of data operations on the selected tape spool pair, and to instruct the drive mechanism to drive a second tape spool pair for performing a second operation on the second tape spool pair while the data operations are being performed.

A magnetic tape in which a tape thickness of the magnetic tape is 5.2 μm or less, and in an environment with a temperature of 32° C. and a relative humidity of 80%, a frictional force F.sub.45° on the surface of the magnetic layer with respect to an LTO8 head measured at a head tilt angle of 45° is 4 gf to 15 gf, and a standard deviation of a frictional force F on the surface of the magnetic layer with respect to the LTO8 head measured at each of head tilt angles of 0°, 15°, 30°, and 45° is 10 gf or less.

A computer-implemented method for detecting sensor-damaging tape media, according to one embodiment, includes acquiring a metric for at least one sensor of a tape drive after performing an operation on a magnetic recording tape, and comparing the metric for the at least one sensor after performing the operation to a metric for the at least one sensor acquired before performing the operation. An action is taken in response to a result of the comparing indicating that a difference between the metrics is in a predetermined range. A product, according to one embodiment, includes a magnetic recording tape, and a memory coupled to the magnetic recording tape. At least one value is stored in the memory, the at least one value being indicative of whether the magnetic recording tape is potentially sensor-damaging.

The time required for recalling the file is reduced when the file is written in a mounted plurality of tapes in comparison to recalling the file when written in a non-mounted plurality of tapes. In the non-mounted state, criteria does not typically exist in order to recall the written file within the plurality of tapes. Embodiments of the present invention provide systems and methods for recalling files based on criteria which considers: the mounted state of a tape; the type of tape; the type of available tape drive; the number of files included in a tape; and the location of the written file in a tape.

A magnetic recording head positioning assembly includes a coarse travel carriage secured to and spaced away from each of a front end assembly and head assembly via sandwiched fine guiding flexures and isolation flexures. The fine guiding flexures permit relative movement between the coarse travel carriage and head assembly. The isolation flexures permit relative movement between the coarse travel carriage and front end assembly. The fine guiding and isolation flexures thus isolate the coarse travel carriage from the front end assembly and head assembly. The assembly further includes dampers sandwiched between the coarse travel carriage and isolation flexures to limit movement of the isolation flexures.
