Abstract

Abstract A magnetic head supporting device which includes a supporter having a resilient spring portion and a rigid beam portion contiguous to the resilient spring portion a flexible member whose one end is attached to the supporter at a portion near its free end; a loading projection provided in the upper surface of the flexible member or in the lower surface of the supporter at a portion near its free end to thereby transmit a loading force from the free end of the supporter to the flexible member; and a magnetic head having a slider attached with reading/writing elements, the magnetic head being fixed to the lower surface of the flexible member, wherein the flexible member is composed of a plate of a polymeric resinous material having conductors for wiring; the conductors are electrically connected to electrodes for the reading/writing elements of the magnetic head, and the plate of a polymeric resinous material is extended on the supporter in its longitudinal direction.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 205 words
A magnetic head supporting device which comprises: a supporter having a resilient spring portion and a rigid beam portion contiguous to said resilient spring; a flexible member having one end attached to said supporter at a portion near a free end of said supporter; a loading projection provided at one of an upper surface of said flexible member and a lower surface of said supporter at a portion near the free end of said supporter to thereby transmit a loading force from the free end of said supporter to said flexible member; and a magnetic head having a slider with reading/writing elements connected thereto, the magnetic head being fixed to the lower surface of said flexible member, wherein said flexible member substantially exclusively comprises a plate of a polymeric resinous material positioned on the supporter and having conductors for wiring, said conductors are electrically connected to electrode for said reading/writing elements of the magnetic head, and wherein the plate of polymeric resinous material extends on the supporter along a longitudinal direction of the supporter, the conductors are embedded in the plate of polymeric resinous material and said plate has a free end portion extending to a lower portion of said rigid beam of said supporter.
Claim 2
Dependent Claim 205 words
A magnetic head supporting device which comprises: a supporter having a resilient spring portion and a rigid beam portion contiguous to said resilient spring; a flexible member having one end attached to said supporter at a portion near a free end of said supporter; a loading projection provided at one of an upper surface of said flexible member and a lower surface of said supporter at a portion near the free end of said supporter to thereby transmit a loading force from the free end of said supporter to said flexible member; and a magnetic head having a slider with reading/writing elements connected thereto, the magnetic head being fixed to the lower surface of said flexible member, wherein said flexible member substantially exclusively comprises a plate of a polymeric resinous material positioned on the supporter and having conductors for wiring, said conductors are electrically connected to electrode for said reading/writing elements of the magnetic head, and wherein the plate of polymeric resinous material extends on the supporter along a longitudinal direction of the supporter, the conductors are embedded in the plate of polymeric resinous material and said plate has a free end portion extending to a lower portion of said rigid beam of said supporter.
Claim 3
Dependent Claim 25 words
The magnetic head supporting device according to claim 1, wherein the plate of polymeric resinous material is attached to the supporter and comprises a damper.
Claim 4
Dependent Claim 32 words
The magnetic head supporting device according to claim 1, wherein an element for an integrated circuit for reading/writing to the magnetic head is positioned on the plate of a polymeric resinous material.
Claim 5
Dependent Claim 22 words
The magnetic head supporting device according to claim 1, wherein the conductor is attached on the plate of a polymeric resinous material.
