Abstract

PURPOSE: To improve sensitivity by coupling a piezoelectric element to the coupling part of a floating head slider body and a slider supporting cymbal spring part and embedding a spherical body into the front end of a slider pressurizing and supporting spring part so that the spherical body pressurizes the slider body.
CONSTITUTION: The spherical body 5 consisting of a metal or ceramics is embedded into the slider pressurizing and supporting spring part 3. The surface 4a of the piezoelectric element 4 coupled and disposed to the rear surface position of the floating slider body 1 is pressurized by this spherical body 5 as the pressurizing front end of the spring part 3. The floating head slider detects the microscillation of the floating head slider 1 generated by the collision against the projection on a magnetic disk and since the spherical body 5 acts as a weight in the oscillation detection of the body 1, the remarkable improvement in the sensitivity is possible. This sensor is particularly effective in the case of detection of the oscillation component of several kHz by the air resonance of the magnetic head slider.
