Abstract

PURPOSE:To make a contact state constant by providing a head slider bonded and overlapped onto the center ring of a gimbals spring, and forming a reinforcing rib surrounding the head slider at the outer circumferential ridge of the center ring. CONSTITUTION:Two half-circular-arc reinforcement ribs (C) are implanted to the outer circumferential ridge of a center ring 2a of a gimbal spring 2 opposite to each other. The top slide face of a head slider 1 is brought into contact with a flexible disk and pressed onto the flexibel disk just under the head slider 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 reinforcement ribs (C) are implanted to the outer circumferential ridge of the center ring 2a of the gimbals spring 2 on the other hand, the stiffness of this part 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] Fig. 3 is a perspective view showing a conventional magnetic head device of this kind. In Fig. 1, (1) is a head slider 1 (1) which is pressed against a flexible disk and records and reproduces information signals.
2) is a gimbal spring in which the negative surface of this head slider is glued onto its center ring (2a), and (2d) is a gimbal spring that is symmetrically protruded from the outer surface of the outermost ring (2C) of this gimbal spring. A fixed part, (2b) is an intermediate ring, (a) and (b) are concentric connecting parts of the rings, and (3) is 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 the center ring (2a) through the head slider (1). When transmitted, this central 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 device 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.

[Means for Solving the Problems] This invention has a plurality of rings provided concentrically from the center to the outer periphery and connected to each other at some connecting parts (a) and (b). A gimbal spring and a head slider (1) polymerized and bonded onto the center ring (2a) of the gimbal spring, and the center ring (2a)
A reinforcing rib (c) surrounding the head slider (1) is formed on the outer peripheral edge of (a).

[Function] In the case of this invention, since the rigidity of the center ring is increased, 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 FIG. 1, (1) is a head slider 1 (1) that is pressed against a flexible disk and records and reproduces information signals.
2) is a gimbal spring made of a thin elastic plate that is provided concentrically from the center to the outer periphery and has a plurality of rings, some of which are connected to each other; (2a) is the center ring of this gimbal spring; Above is the head slider (
1) is bonded by polymerization, and reinforcing ribs (c) are formed on the outer periphery by bending in a semicircular arc shape to surround the head slider (1).

(2b) shows the intermediate ring, (2d) the fixing part provided symmetrically on the outer side of the outermost ring (2c) of the gimbal spring, (3) shows the rotation direction of the flexible disk, and (a) and (b) are connecting portions of the above-mentioned 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 below 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, on the outer peripheral edge of the center ring (2a) in the gimbal spring (2), there are two semicircular arc-shaped reinforcing ribs (c).
Since the flexible disks are installed vertically facing each other, the rigidity of this part is large, and therefore, the minute vibrations generated in the flexible disk are transmitted through the head slider (1) to the center ring (2).
Even if the signal is transmitted to a), 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, and as a result, the head slider and This has the effect that the contact state of the flexible disk becomes constant, allowing accurate recording and reproduction of information signals.
