Space saving configuration of a printed cirucit board for a magnetic

Abstract

A disk drive has a pair of transducers mounted to respective planar flexure seats and electrically connected to respective flexible printed circuit boards for data transfer with the opposite sides of a rotating flexible magnetic disk. One of the transducers, mounted to a pivoted load arm on a carriage, is moved away from the other transducer when the disk is being loaded in and unloaded from the disk drive. In order to prevent the conductive pattern on the circuit board for this one transducer from contacting the metal made top wall of the disk drive casing, the circuit board is shaped to include a major portion disposed on the back side of the flexure seat, opposite to the front side on which the transducer is mounted. The circuit board is further provided with a first pair of flaps which extend in opposite directions from the major portion and which are folded onto the front side of the flexure seat, and a second pair of flaps which extend right angularly from the first pair of flaps and which are folded, after having been folded together with the first pair of flaps onto the first side of the flexure seat, back onto the second side thereof so as to cover parts of the conductive pattern on the major portion. The transducer has its leads soldered to the conductive pattern on the first pair of flaps.
