Abstract
An actuator assembly for a magnetic recording disk file and method of fabricating same. A sleeve surrounds and is axially moveable relative to a stator to control the axial position of a head/arm assembly relative to a magnetic recording disk. The sleeve is separated from said stator by a gas-bearing film. Electronic circuit components are mounted on a canister that surrounds said sleeve and is substantially thermally isolated from said sleeve to dissipate heat generated by said components. The canister is in the form of a hollow rectangle which surrounds the rectangle sleeve with clearance and is secured to the sleeve at a minimum number of points to permit cooling air to flow through the clearance space with minimal obstruction. A flexible flat conductive input/output cable is secured to three sides of the canister, and a flexible flat conductive power cable is secured to the remaining side of the canister.
