Abstract:
An information recording disk apparatus, comprising:at least an information recording disk for recording information; at least a read/write head for writing/reading the information on/from said information recording disk; a head supporting arm assembly for supporting said read/write head; a pivot shaft for supporting pivotally said head supporting arm assembly; an actuator for driving said head supporting arm assembly; and at least a pair of acceleration detectors for detecting acceleration in two directions extending discretely in parallel to each other, wherein respective ones of said pair of acceleration detectors is disposed on a circuit board at positions proximate to said information recording disk relative to said pivot shaft as viewed in a longitudinal direction of a box-like casing of said information recording disk apparatus so that a rotation center of said information recording disk is disposed between said pair of acceleration detectors, and said pair of acceleration detectors is disposed on a line which extends through the rotation center and is perpendicular to a rotation axis of said information recording disk.
