Compact head and disk assembly

摘要

A compact, sealed head and disk assembly for a rotating non-removable disk data storage subsystem includes a flat and thin rigid generally rectangular box housing having a length not greater than approximately 173 millimeters, a width not greater than approximately 102 millimeters and a height not greater than approximately 24.5 millimeters,; a thin spindle motor mounted within the form factor of the housing; at least one magnetic media data storage disk having a diameter of approximately 95 millimeters in the housing and mounted directly to the spindle for rotation; a limited angular displacement rotary actuator subassembly including a substantially planar limited displacement rotary actuator motor; and, a cover for closing and sealing the housing.
