Magnetic read/write head and magnetic read/write apparatus having same

摘要

A magnetic read/write head includes: a slider having an ABS, a surface at an leading edge, and a surface at an trailing edge; a piezoelectric device arranged on the surface at the trailing edge of the slider; and a magnetic read/write element arranged on the piezoelectric device. The piezoelectric device, upon application of voltage, is displaced asymmetrically with respect to a displacement axis which is on the surface at the trailing edge of the slider and which is perpendicular to the surface of the magnetic recording medium. With this asymmetrical displacement of the piezoelectric device, the magnetic read/write element rotates about the rotation axis perpendicular to the surface of the magnetic recording medium.
