Abstract: A magnetic head device which can accommodate higher data transfer rates can be implemented by using lead wires. A magnetic head device 1 according to the present invention includes a head slider 3 having a magnetic head 2 having a data reading element and a data writing element, a reading lead RL for transferring data between the data reading element and external devices, the reading lead configured by a pair of lead wires which are twisted together, and a writing lead WL for transferring data between the data writing element and external devices, the writing lead configured by a pair of lead wires which are untwisted but arranged in parallel to each other. Thus, the magnetic head device can accommodate higher data transfer rates by using the writing lead WL configured by a pair of lead wires which are untwisted but arranged in parallel to each other.

Abstract: The present invention prevents a head/slider assembly fixed on a flexure of a head suspension assembly from having an undesired pitching motion when an unexpected excess shock is applied to a hard disk device when the head suspension is at the best position of the unload ramp. A disk drive device in accordance with the present invention comprises: a rotating data recording disk; a head suspension assembly containing a front portion and a rear portion, with the front portion being provided with a tab; a device coupled to the rear portion of the head suspension assembly to move the front portion between an inner most position and an outer most position along a radial direction of the rotating data recording disk; a ramp element containing a support surface for engaging with the tab of the front portion of the head suspension assembly when the front portion is moved to the outer most position; and a flexure mounted on said front portion of the head suspension assembly, and having a front portion disposed towards the tab of the head suspension assembly and a rear portion disposed towards the rear portion of the head suspension assembly.
