Title:
WIRING STRUCTURE BETWEEN MAGNETIC HEAD AND SIGNAL PROCESSING CIRCUIT IN DISK UNIT
Document Type and Number:
Japanese Patent JP2756222
Kind Code:
B2
Abstract:
PURPOSE: To reduce a noise by providing a first and a second inductance element in a first and a second signal paths connecting a magnetic head and a signal processing circuit.
CONSTITUTION: This device is constituted with first signal paths 12, 11a and second signal paths 13, 11b which connect a magnetic head 10 and a signal processing circuit 19 in a disk unit, a magnetic head having a first inductance element 21a provided between the first signal paths 12, 11a, and a second inductance element 21b provided between the second signal paths 13, 11b and magnetically coupling with the first inductance element 21a, and a signal processing circuit. Thereby, a direct current component is never cut in the signal paths 12, 11a and 13, 11b. Therefore, a noise induced in each signal path can be reduced.
