Abstract

PURPOSE:To make a contact state constant by providing a gimbals spring having plural rings, and overlapping and bonding a guard with a large diameter projecting from the outer circumferential face of a head slider onto its center ring, thereby reinforcing the center ring. CONSTITUTION:A guard 1a with a large diameter projecting from the outer circumferential face of a head slider 1 is overlapped and bonded onto its center ring 2a of a gimbals spring 2. The top slide face of the slider 1 is brought into contact with a flexible disk and pressed onto the flexible just above with the spring 2. In such a state, the information signal of the flexible disk is able to be recorded/reproduced by the slider 1. Since the guard 1a of the slider 1 is overlapped and bonded onto the ring 2a of the spring 2, the stiffness is large and even when minute vibration caused on the flexible disk is delivered to the ring 2a via the slider 1, the center ring is not resonated. Thus, the information signal is accurately recorded and reproduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic head device using a gimbal spring.

[Prior Art] Figs. 3 and 4 are a plan view and a front view showing a conventional magnetic head device of this type, and in the figures, (1) is pressed against a flexible disk to record and reproduce information signals. Head slider 1 (2) is a gimbal spring with the - side of this head slider fixed on its center ring (2a), and (2d) is a gimbal spring with the outermost ring (2C) of this gimbal spring on the left and right sides. Fixed parts protruding symmetrically (2
b) shows the intermediate ring, (a) and (b) concentric connecting parts of the rings, and (3) shows the rotation direction of the flexible disk.

By the way, since the gimbal spring (2) is flat and thin and has low rigidity, minute vibrations generated in the flexible disk (not shown) are transmitted to its center ring (2a) via the head slider (1). When this occurs, the center ring (2a) resonates and generates large vibrations.

[Problems to be Solved by the Invention] Since the conventional magnetic head device is configured as described above, the contact state between the head slider (1) and the flexible disk is maintained constant due to the resonance of the center ring (2a). However, there is a problem in that accurate recording and reproduction of information signals is hindered.

This invention was made to solve the above problems, and is a magnetic head that eliminates the resonance of the center ring, maintains a constant contact state between the head slider and the flexible disk, and can accurately record and reproduce information signals. The purpose is to obtain equipment.

[Means for Solving the Problems] In the case of the present invention, a center ring of a gimbal spring has a plurality of rings provided concentrically from the center to the outer periphery and connected to each other at some connecting portions. A large-diameter flange protruding from the outer circumferential surface of the head slider is bonded to the top of the head slider to increase the rigidity of the center ring.

[Function] In the case of the present invention, since the center ring has increased rigidity, the center ring does not resonate due to minute vibrations generated by sliding of the flexible disk.

[Example] An example of the present invention will be described below. That is, in FIGS. 1 and 2, the head slider 1 (1a) that is pressed against the flexible disk and records and reproduces information signals is a large-diameter collar protruding from the outer peripheral surface of the head slider. Department.

(2) are provided concentrically from the center to the outer periphery,
A gimbal spring (2a) is made up of a thin elastic plate having a plurality of rings connected to each other; (2a) is the center ring of the gimbal spring; 1a) is polymerically bonded thereon. (2b) shows the intermediate ring, (2d) shows the fixing part projecting symmetrically on the outside of the outermost ring (2C) of the gimbal spring, (3) shows the rotation direction of the flexible disk, and (2d) shows the rotation direction of the flexible disk. ) and (b) are the connecting parts of each of the above rings.

Next, the operation will be explained. The top sliding surface of the head slider (1) contacts the flexible disk in the state shown in FIG. 1, and is pressed against the flexible disk (not shown) directly above by a gimbal spring (2). In this state, the head slider (1) can record and reproduce information signals on the flexible disk.

By the way, the center ring (2a) of the gimbal spring (2)
) The flange (1a) of the head slider (1) is polymerized and bonded onto the top of the head slider (1), so it has high rigidity, so minute vibrations generated in the flexible disk are absorbed by the head slider.
Even if it is transmitted to the center ring (2a) via (1), this center ring will not resonate.

[Effects of the Invention] Since the magnetic head device of the present invention is configured as described above, the center ring of the gimbal spring does not resonate due to minute vibrations generated in the flexible disk.
This has the effect that the contact state between the head slider and the flexible disk is constant, allowing accurate recording and reproduction of information signals.
