Abstract: A transducer assembly includes a slider (11) having a reduced height leading portion (12) that provides for gimballed connection to a suspension load beam (30) and a full height rear portion for the transducer coil windings (21). The transducer assembly is supported by a suspension which includes a single piece combined gram form and load beam (30) with the entire head-suspension assembly being contained within the height of the full height portion of the slider so as to minimise the overall height of the head-suspension assembly.

Abstract: A direct access storage device includes at least one disk mounted for rotation about an axis and having opposed disk surfaces for storing data. A magneto-resistive (MR) transducer head is mounted for movement across each respective disk surface for writing to and for reading data signals from the disk surface. Each MR transducer head includes a write element and a read element. A preamplifier, associated with the MR transducer head, amplifies read and write signals of the read element and the write element. A flex cable couples the read and write signals between the preamplifier and the MR transducer heads. The flex cable includes a common read return signal line for each sequential pair of the MR transducer heads.

Abstract: A head suspension assembly for use in a disk drive having a load and unload ramp, the head suspension assembly including a load beam, a cover having a load and unload tang, a coating sandwiched between the cover and the load beam, and a head lead wire extending through the coating. In a preferred embodiment, the coating is a visco-elastic thermoplastic adhesive and the cover is a constraining material; whereby the cover is adhered to the load beam and undesired vibrations of the head suspension assembly are dampened. In a method of fabricating the head suspension assembly, the cover is placed over the load beam after the coating is applied and after the head lead wire is strung over the load beam, and then the cover is adhered to the load beam by heating the coating, preferably by placing a heated platen over the cover. Consequently, the load and unload tang, which is part of the cover, is not an obstacle when routing the head lead wire over the load beam and bonding the wire to a slider, and the head suspension assembly fabrication process can be automated.
