Document Type and Number:
Japanese Patent JPH06295418
Kind Code:
A
Abstract:
PURPOSE: To enhance the reproduction output of a combined magnetic head at the time of magnetic recording and reproduction.
CONSTITUTION: A recording head 17 is formed on a slider 11 and an MR head 15 is formed on the head 17. By this structure, a soft magnetic material having high saturation magnetization and requiring heat treatment can be used as the material of the magnetic core of the recording head. The distance between the reproducing head and a medium is made shortest and spacing loss is reduced at the time of reproduction.
