Title: Magnetic head
Inventor: SATO YUICHI
IPC: G11B5/39
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To relatively simplify the structure, to sufficiently enlarge the reproducing output voltage and to simultaneously reproduce multi-valued information by providing with an information reproducing element capable of simultaneously detecting plural signal magnetic fields from a recording medium. SOLUTION: A high frequency magnetic field is applied to a magnetic layer 10 by causing an electric current to flow into the non-magnetic conductive layer 11 served also as a detecting line. The magnetic permiability of the magnetic layer 10 applied the high frequency magnetic field is varied with the recording magnetic field given from the recording medium as an external magnetic field. For this purpose, since the impedance of the information reproducing element E is varied, the variation of the external magnetic field is resultantly detected as the variation of an output voltage. In the case of using only one information reproducing element, when simultaneously reproducing the signal magnetic field from recording tracks 21, 22, 23 having mutually different recording track width, eight kinds of reproducing voltages are obtained.  Here, when the recording track width of recording tracks 21-23 is set so as to be 1:2:4 and the reproducing output voltage value is set to 1:2:4, eight-valued information are simultaneously reproduced.
