Embodiment Construction

[0059] The magnetic head suspension of the present invention satisfies the required vibration characteristics by setting the track on the elastic part of the load beam, and the track has a deformable part through the presence of a longitudinal curve on the track to prevent the distortion of the magnetic head suspension.

[0060] refer to Figures 1 to 3 Let's understand the head suspension in the first embodiment of the present invention, wherein figure 1 is the perspective view of the head suspension, Figure 2A is a partially enlarged perspective view of the head suspension, Figure 2B is along figure 1 The profile of the II-II line, Figure 2C is a modified sectional view of the first embodiment, and image 3 is another view of the head suspension of the first embodiment.

[0061] Figures 1 to 3 The head suspension 1 in is for a 2.5-inch magnetic disk, for example, it has a load beam (LB) 3 , a base plate 5 and a flexure 7 .

[0062] The load beam 3 applies a load...

Abstract

The head suspension includes a base plate turned around a spindle, a load beam, and a flexure. The load beam includes the rigid part, a resilient part, and a head. A base end of the rigid part is attached to the resilient part, which is supported with the base plate. The head is for writing and reading data to and from a disk and is positioned at a front end of the rigid part to receive load fromthe load beam. The flexure is attached to the load beam and supports the head. A rail is formed along each side edge of the rigid part by bending the side edge in a thickness direction of the rigid part. The rail is continuous from the front end to the base end of the rigid part. The base end of the rigid part widens to form a wide part. The rail has a longitudinal curve around the start of the wide part. The longitudinal curve is provided with a deformable part that is more easily deformable in the longitudinal and vertical directions of the rail than the remaining parts.

Description

technical field [0001] The present invention relates to a magnetic head suspension of a hard disk drive integrated in an information processing device such as a personal computer. Background technique [0002] The magnetic head suspension of the hard disk drive includes a load beam, a magnetic head supported by the load beam, and a slider fixed on the magnetic head. The head suspension has a shock characteristic that determines to lift the slider from the hard disk surface when a shock is applied. The vibration characteristics of the head suspension depend on the weight of the load beam. [0003] For example, the first head suspension has a load beam with a thickness (t) of 51 μm and a length (1L) of 7 mm, and the load applied by the beam to the head is 2.5 gf, and the second head suspension has a thickness (t) of 30 μm, a length of 5.5 mm A load-bearing beam of length (1L) with a load of 2.5gf. If a shock of 1 millisecond duration (1 millisecond of a half wave) is applie...
