Abstract: A detection device includes a processing device and a storage medium. The processing device stores a result of reading a servo pattern by a servo reading element from a magnetic tape in which the servo pattern is recorded in a servo band, in the storage medium as an ideal waveform signal indicating an ideal waveform, acquires a servo band signal which is a result of reading the servo band by the servo reading element, and detects a servo pattern signal indicating the servo pattern by comparing the ideal waveform signal stored in the storage medium with the servo band signal.

Abstract: A magnetic tape cartridge includes a case in which a magnetic tape is accommodated and a storage medium provided in the case. At least one of reading or writing of data is performed by a plurality of magnetic elements, which are linearly disposed, with respect to the magnetic tape pulled out from the case. A disposition direction of the plurality of magnetic elements is tilted toward an entire length direction side of the magnetic tape with respect to a width direction of the magnetic tape. The storage medium stores tilt feature information indicating a feature of tilt of the disposition direction with respect to the width direction.

Abstract: A magnetic tape cartridge includes a magnetic tape, and a storage medium in which information on the magnetic tape is stored. The magnetic tape has a recording surface. Data is recorded in the recording surface by a magnetic head in a state in which the magnetic tape is made to travel. The magnetic head is disposed at an inclined posture with respect to a width direction of the magnetic tape along the recording surface. Angle adjustment information obtained before the data is recorded in the recording surface is stored in the storage medium. The angle adjustment information is information for adjusting an angle at which the magnetic head is inclined with respect to the width direction along the recording surface.

Abstract: A detection device includes a processing device and a storage medium. An ideal waveform signal indicating an ideal waveform of a servo pattern signal which is a result of reading a servo pattern recorded in a servo band of a magnetic tape by a servo reading element is stored in advance in the storage medium. The processing device acquires a servo band signal which is a result of reading the servo band by the servo reading element, and detects the servo pattern signal by comparing the servo band signal with the ideal waveform signal.

Abstract: A detection device includes a processing device and a storage medium. The processing device stores a result of reading a reference servo pattern by a servo reading element in the storage medium as an ideal waveform signal, acquires a servo band signal which is a result of reading a servo pattern recorded in a servo band by the servo reading element, and detects a servo pattern signal which is a result of reading the servo pattern by the servo reading element by comparing the ideal waveform signal with the servo band signal. The reference servo pattern is recorded between a BOT section and an EOT section in a longitudinal direction of the magnetic tape.

Abstract: A magnetic tape cartridge includes a case that accommodates a magnetic tape on which a plurality of servo bands and a plurality of data bands are formed, servo patterns being recorded in the servo bands, and a memory provided in the case. The memory stores servo pattern interval-related information related to a servo pattern interval determined for each of the plurality of data bands included in the magnetic tape. The servo pattern interval is commonly used for a plurality of division areas obtained by dividing the data band in a width direction of the magnetic tape, and is a representative interval between a first servo pattern and a second servo pattern.

Abstract: A magnetic head includes a pair of servo reading elements corresponding to a pair of servo bands adjacent to each other in a width direction. A processor acquires a first signal based on a first result obtained by reading a servo pattern in a first servo band by a first servo reading element included in a pair of servo reading elements, acquires a second signal based on a second result obtained by reading the servo pattern in a second servo band by a second servo reading element included in the pair of servo reading elements, and outputs a deviation amount signal corresponding to a deviation amount in time between the first signal and the second signal.
