Claim 6:
7. The detection device according to claim 6,
wherein the ideal waveform signal is classified into a first ideal waveform signal corresponding to the first linear magnetization region and a second ideal waveform signal corresponding to the second linear magnetization region,
the servo pattern signal includes a first linear magnetization region signal which is a result of reading the first linear magnetization region by the servo reading element, and a second linear magnetization region signal which is a result of reading the second linear magnetization region by the servo reading element,
the processing device includes a first detection circuit and a second detection circuit which are connected in parallel,
the first detection circuit
acquires the servo band signal, and
detects the first linear magnetization region signal by comparing the acquired servo band signal with the first ideal waveform signal, and

the second detection circuit
acquires the servo band signal, and
detects the second linear magnetization region signal by comparing the acquired servo band signal with the second ideal waveform signal.
