ABSTRACT:
An enclosure for a disk drive which may serve as an external store of a computer is constituted by a two-sided printed circuit board, a frame, and a top board, the printed circuit board being loaded with a disk driving section. The printed circuit board, frame, and top board have substantially the same coefficient of linear thermal expansion. The printed circuit board is prevented from being deformed by heat, so that the accuracy of the disk driving section is maintained to insure stable recording and playback.
