ABSTRACT:
A magnetic head assembly having two magnetic heads for use on two sides of a magnetic head and arranged so as to use one common circuit to process signals from the two magnetic heads and so that the magnetic heads can be manufactured at a reduced cost. The magnetic heads are disposed on the two sides of the magnetic disk so that magnetic core blocks of the magnetic heads are located at different distances from the center of rotation of the magnetic disk. Recording/reproduction gaps of the magnetic core blocks are formed so that the depth of the recording/reproduction gap of the magnetic core block closer to the center of rotation of the magnetic disk is larger than the depth of the recording/reproduction gap of the other magnetic core block.
