Abstract

Abstract A floating magnetic head of the type in which a slider is joined to the free end of a magnetic head support device includes wings provided in the free end section of the magnetic head support device and engaged with notches provided in slider sections excluding the ABS surface thereof, thereby providing a high level of resistance to impacts and vibrations. Further, a floating magnetic head of the type in which a slider having a magnetic core is attached to the front end of a suspension element through the intermediation of a flexure includes: a recess formed in the middle section of a flexure attachment surface of the slider and having a bottom surface to which the flexure is attached; walls formed on both sides of the recess; and grooves for weight balance adjustment formed in the walls, whereby the center of gravity of the slider coincides with the position of the load protuberance not only in the height direction of the slider but also in the horizontal direction of the same, so that the a stable floating attitude can be maintained during seeking operation, etc.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 129 words
A floating head assembly for supporting a read/write head over an information-bearing disk in a disk drive device, the floating head assembly comprising: a head supporting member having a free end; a flexure connected to the free end of the head supporting member, the flexure including a body and a pair of wings extending from the body; and a slider having an upper surface movably connected to the flexure and a pair of L-shaped members extending from the upper surface such that the L-shaped members and the upper surface define a pair of notches for receiving the wings; wherein when the slider is floating in a normal position over the information-bearing disk, the wings are located within the notches and separated from the L-shaped members and the upper surface.
Claim 2
Dependent Claim 129 words
A floating head assembly for supporting a read/write head over an information-bearing disk in a disk drive device, the floating head assembly comprising: a head supporting member having a free end; a flexure connected to the free end of the head supporting member, the flexure including a body and a pair of wings extending from the body; and a slider having an upper surface movably connected to the flexure and a pair of L-shaped members extending from the upper surface such that the L-shaped members and the upper surface define a pair of notches for receiving the wings; wherein when the slider is floating in a normal position over the information-bearing disk, the wings are located within the notches and separated from the L-shaped members and the upper surface.
Claim 3
Dependent Claim 19 words
A floating head assembly according to claim 1, wherein the flexure is connected directly to the head supporting member.
Claim 4
Dependent Claim 28 words
A floating head assembly according to claim 1, further comprising an adapter fixedly connected to the head supporting member, wherein the flexure member is connected to the adapter.
Claim 5
Dependent Claim 19 words
A floating head assembly according to claim 1, wherein the disk drive device is an optical disk drive device.
Claim 6
Dependent Claim 19 words
A floating head assembly according to claim 1, wherein the disk drive device is a magnetic disk drive device.
