Detection device, inspection device, magnetic tape cartridge, magnetic tape, magnetic tape drive, magnetic tape system, detection method, inspection method, and program

A magnetic tape cartridge comprising:

• a memory;
• and
• a magnetic tape in which a reference servo pattern is recorded,
• wherein a detection device having a processing device and a storage medium is used for the magnetic tape cartridge,
• the processing device
• stores a result of reading the reference servo pattern by a servo reading element from the magnetic tape, in the storage medium as an ideal waveform signal indicating an ideal waveform,
• acquires a servo band signal which is a result of reading a servo pattern recorded in a servo band of the magnetic tape 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 stored in the storage medium with the servo band signal,
• the ideal waveform signal is stored in the memory,
• the magnetic tape has a BOT section and an EOT section,
• the reference servo pattern is recorded between the BOT section and the EOT section in a longitudinal direction of the magnetic tape,
• the magnetic tape has a base film, and
• the base film is made of polyethylene terephthalate, polyethylene naphthalate, or polyamide.
