  • Magnetic head device and lead wire
    Patent number: 6801401
    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.
