Problems solved by technology

Also, higher write frequencies lead to drastic changes in the voltage applied to the write head element
Therefore, crosstalk occurs from the write side to the read side, which brings about a tendency to degrade characteristics in the read head element

Abstract

The composite thin film magnetic head is provided with: a write head element; a pair of terminal pads for the write head element; a pair of lead conductors for the write head element for electrically interconnecting the write head element and a pair of the terminal pads for the write head element; a read head element; a pair of terminal pads for the read head element; and a pair of lead conductors for the read head element for electrically interconnecting the read head element and a pair of the terminal pads for the read head element, and a pair of the lead conductor for the write head element and a pair of lead conductor for the read head element are formed to be patterns not overlapped with each other via only an insulation layer.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Japanese Patent Application No. 2004-103865 filed on March 31, 2004, which is incorporated herein by reference. technical field [0003] The present invention relates to a composite thin film magnetic head comprising a write head element and a read head element. Background technique [0004] Recently, in order to satisfy demands for making a hard disk drive device (HDD) larger in capacity and smaller in size, higher recording density in a magnetic disk and further miniaturization of a head gimbal assembly (HGA) including a magnetic head are required. [0005] However, the greater miniaturization of HGAs causes crosstalk problems between the write and read sides. In particular, the further miniaturization of the magnetic head element, due to the reduction of the cross-sectional area of ​​the element, and the reduction of heat dissipation, causes an increase in the current density f...
