Classification: CPC G | IPC G

Claim 15:
16. An inspection device comprising:
the detection device according to claim 13, which is used together with a servo pattern recording device; and
an inspection processor that is configured to inspect a servo band, on which the servo pattern is recorded in a magnetic tape, based on the servo signal detected by the detection device,
the servo pattern recording device comprising:
a pulse signal generator; and
a servo pattern recording head, wherein:
the pulse signal generator generates a pulse signal,
the servo pattern recording head has a substrate and a plurality of gap patterns formed on a front surface of the substrate, and records a plurality of servo patterns in a width direction of the magnetic tape by applying a magnetic field to the magnetic tape from the plurality of gap patterns in response to the pulse signal,
the plurality of gap patterns are formed on the front surface along a direction corresponding to the width direction,
the gap patterns are at least one straight line region pair,
a first straight line region, which is one straight line region of the straight line region pair, and a second straight line region, which is the other straight line region of the straight line region pair, are inclined in opposite directions with respect to a first imaginary straight line along the direction corresponding to the width direction on the front surface,
the first straight line region has a steeper inclined angle with respect to the first imaginary straight line than the second straight line region,
positions of both ends of the first straight line region and positions of both ends of the second straight line region are aligned in the direction corresponding to the width direction of the magnetic tape,
the plurality of gap patterns deviate from each other at 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, and
the substrate is inclined along the magnetic tape with respect to the first imaginary straight line at an angle at which deviation at the predetermined interval is absorbed.
