Ribbon Cable Head

A low-cost magnetic head is formed from ribbon cable bent upon itself with prewound coils slipped over the bends.

The starting material is a ribbon cable having a surface of wrought plated or vacuum deposited magnetic material which may be encapsulated, bonded or otherwise deposited onto a flexible insulating material such as polymeride. Individual strips of the magnetic material are formed by photoetching, thereby precisely positioning or locating the strip centerlines. The ribbon is sheared (Step 1) into two parts, and alternate strips are removed as required to maintain inter-track spacing and to provide inter-track shielding (Step 2). Prewound coils are slipped over the remaining individual magnetic strips, and both ends of the ribbon are clamped in a suitable fixture. A wrought shim or vacuum deposited material is added to produce a read/write gap, the ribbon is bent in half, and machining removes all excess material (Step 3). A housing may be added to protect the head and to produce good wear characteristics.
