Abstract

Typically a disk file has a transducer 1 attached to a suspension member 2 which is, in turn, attached to an arm of a positioning assembly 3. In order to precisely align the transducer relative to the tracks of the disk, not shown, the connection between the suspension member 2 and the positioning arm 3 is made adjustable.

Adjustable Suspension Mount for Head Assembly

Typically a disk file has a transducer 1 attached to a suspension member 2 which is, in turn, attached to an arm of a positioning assembly 3. In order to precisely align the transducer relative to the tracks of the disk, not shown, the connection between the suspension member 2 and the positioning arm 3 is made adjustable.

One low-cost means of attachment is shown in the figure. A resilient clip 4 is fastened to the end of the suspension member 2 for attachment to the positioning arm 3. The clip 4 can be made from spring steel, for instance, providing a spring force with an adequate gripping action such that the assembly can be tested according to specifications, before the suspension member 2 is permanently fastened to the positioning arm 3.

The final precise head alignment is achieved by sliding the clip 4 in and out or across the positioning arm 3. When this desired head position is achieved, the clip 4 can be permanently fastened to the positioning arm 3 by epoxy bonding the suspension member 2 to the positioning arm. Any unit found defective during the testing can be easily replaced by unclipping the defective assembly.
