Embodiment Construction

[0050] The present invention satisfies the desired shock characteristics by providing the elastic portion of the load beam (LB) with an extended head suspension.

[0051] The head suspension device of the hard disk drive according to an embodiment will be described in detail below.

[0052] figure 1 is a perspective view showing the first face of the head suspension according to this embodiment, figure 2 is a perspective view showing the second face of the head suspension of this embodiment, and image 3 is a plan view showing the first face of the head suspension of this embodiment.

[0053] Figures 1 to 3 The head suspension shown is for a 1-inch disk, for example, with a load beam 3 , arms 5 and bends 7 .

[0054] The load beam 3 applies load to the magnetic head 8 . A magnetic head 8 is arranged at the front end of the load beam 3 in order to write data to and read data from the disk. The load beam 3 includes a rigid part (or hard part) 9 and an elastic part (or h...

Abstract

A head suspension includes an arm turned around a spindle, the load beam, and a flexure. The load beam includes a rigid part, a resilient part, and a head. The rigid part has a body and a joint. The joint is connected to a first end of the resilient part that is supported with the arm. The head is for writing and reading data to and from a disk and is positioned at a front end of the load beam toreceive load from the load beam. The flexure is attached to the load beam and supports the head. A rail is formed along each side edge of the body of the rigid part and rises in a thickness directionof the body. The first end of the resilient part has extensions that extend over the joint of the rigid part toward the body of the rigid part. The extensions are fixed to the body of the rigid part.

Description

technical field [0001] The present invention relates to a hard disk drive head suspension installed in an information processor such as a personal computer. Background technique [0002] The magnetic head suspension device of the hard disk drive includes a load beam, a magnetic head supported by the load beam, and a slider attached to the magnetic head. The head suspension has a shock characteristic that ensures that the slider lifts off the hard disk surface when 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 thickness (t) of 51 μm, a length (1L) of 7 mm, and a load beam with a gram load of 2.5 gf applied to the head by the load beam, while the second head suspension has a thickness (t) of 30 μm. ), a length (1L) of 5.5mm, and a load-carrying beam of 2.5gf gram load. If a shock of 1 ms duration (half wavelength 1 ms) is applied to these head suspensions, t...
