Magnetic recording/reproducing apparatus having an offset head chip

摘要

A magnetic recording/reproducing apparatus according to the present invention includes: a fixed cylinder; a rotary cylinder rotatably supported by the fixed cylinder, the rotary cylinder including a disk-shaped magnet in which first areas having a first pole and second areas having a second pole opposite to the first pole are alternately arranged; and a head chip attached to the rotary cylinder, wherein the fixed cylinder has a stator coil for generating a magnetic force between the stator coil and the disk-shaped magnet, thereby rotating the rotary cylinder, and the head chip is placed on the rotary cylinder so that a phase angle theta between a virtual plane including a center of a head gap of the head chip and a rotation axis of the rotary cylinder and one of two polar boundary planes sandwiching the area where the virtual plane traverses satisfies 0.4 alpha
