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, and the conductors are electrically connected to electrodes for the reading/writing elements of the magnetic head.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 221 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 portion and being made of a polymer resinous material; 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 and 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 having conductors for wiring, and wherein said conductors are electrically connected to electrodes for said reading/writing elements of the magnetic head, said plate has a rear end portion thereof extending on said rigid beam portion of the supporter through an opening formed in said supporter, and said rear end of said plate is on an upper surface of the rigid beam portion and has a free end portion extending to a lower portion of said rigid beam portion of said supporter.
Claim 2
Dependent Claim 221 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 portion and being made of a polymer resinous material; 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 and 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 having conductors for wiring, and wherein said conductors are electrically connected to electrodes for said reading/writing elements of the magnetic head, said plate has a rear end portion thereof extending on said rigid beam portion of the supporter through an opening formed in said supporter, and said rear end of said plate is on an upper surface of the rigid beam portion and has a free end portion extending to a lower portion of said rigid beam portion of said supporter.
Claim 3
Dependent Claim 27 words
The magnetic head supporting device according to claim 1, wherein said conductors for wiring are embedded in said plate and said plate comprises a polymeric resinous material.
Claim 4
Dependent Claim 26 words
The magnetic head supporting device according to claim 1, wherein said conductors for wiring are connected to said electrodes and said conductors comprise beam lead conductors.
Claim 5
Dependent Claim 18 words
The magnetic head supporting device according to claim 1, wherein said flexible member is made of polymide resin.
