Abstract
A thin film magnetic read/write head/arm assembly and method of manufacturing the same is disclosed herein. Contact soldering of the opposite to disk side of the read/write head to a cable in laminate relationship to the suspension arm, or a polyimide strip with conductors deposited thereon provides both electrical interconnection and mechanical support. Semiconductor devices can also be intermediately soldered between the head and cable for maximum noise suppression.
Claims3
In a magnetic disk data storage system wherein a suspension arm supports and positions a thin film head/slider combination to specific tracks at particular radii on a magnetic disk and wherein said head/slider combination is electrically connected to external control circuitry, the improvement to said suspension arn and head/slider assembly comprising:
- (a) a head/slider combination having solder contact pads and an electrically conductive path formed on a top surface opposite to the surface intended to face a disk of said head/slider, the electrically conductive path providing electrical connection between the head and at least one of the solder contact pads, and
- (b) a cable wiring harness attached in a laminate relationship to said suspension arm said wiring harness being contact solder connected to said head/slider to thereby provide both mechanical support and electricl interconnection between the top surface of said head/slider and said cable wiring harness and suspension arm.
