Abstract
A rotary disk storage system is provided for use with portable or laptop computers which is designed to achieve an overall maximum height ('Z-height') not greater than 17 mm. In attaining this result, the top cover and lower base plate of the housing of this rotary disk storage system are sealed by a pressure sensitive adhesive which permits the top cover to 'float' on the lower base plate. Moreover, the reduced overall height is attained by forming the spin motor which rotates the magnetic disks integrally with the lower base plate. Further, IC chips are mounted on the printed circuit board to provide signal processing to a host computer, these IC chips being mounted on one side of the printed circuit board to face the lower base plate of the disk storage system. When the rotary disk storage system of the present invention is assembled, each of these IC chips is accommodated within differentially-sized pockets formed in the bottom surface of the lower base plate.
