Title: Magnetic signal reproducing method
Inventor: ITOU MICHI
IPC: G11B11/10
Filed: 1993-07-21
Abstract: PURPOSE:To increase recording density by preventing an output change and a Barkhausen noise due to the traveling speed of a recording medium and temp. change. CONSTITUTION:A response element 25 is magnetized by the magnetic flux from a magnetic tape 30. A light whose amplitude directions are made uniform via a polarizing filter 23a from a light-projection part 21 by being passed through the filter is made incident on a prism 24 and reflected by a reflection film 26 and strikes the response element 25 at the angle of about 50 deg. and is reflected. Then, the plane of polarization in the reflected light from the response element 25 is rotated by a prescribed angle in a prescribed direction. The reflected light is selected with a polarizing filter 23b in accordance with the rotation angle of the plane of polarization. Since a light receiving part 22 receives the reflected light of the plane of polarization passed through the polarizing filter 23b, the difference of the rotation angle of the plane of polarization is detected. Thus, a magnetooptic read-out head reproduces information signals on the magnetic tape 30.
