High Density Laminated Head

A magnetic head for reading and writing very high-density information on magnetic media is constructed by staggering the windings, while maintaining qual-length magnetic paths and in-line gaps.

The head is constructed of read and write sections for each track on the media. Read sections comprise two types of C-shaped pole pieces, each having the same length perimeter. The write sections have a complementary shape and are assembled together with the read sections by abutting both sections against center sections to form read, write and back gaps.

Prior to assembly, windings are slipped over one leg of each Pole piece. The maximum number of winding turns is limited by the clearance between adjacent windings. Staggering of the coils permits densities on the order of 100 tracks per inch. If desired, shielding may be provided between, or around, the coils.
