Abstract

A compact magnetic head for reading, writing, and erasing high-density analog information on a magnetic media is constructed by positioning the axis of core coils 90 degrees relative to one another, and maximizing the air gap spacing between poles.

Cross Pole Magnetic Head

A compact magnetic head for reading, writing, and erasing high-density analog information on a magnetic media is constructed by positioning the axis of core coils 90 degrees relative to one another, and maximizing the air gap spacing between poles.

During manufacture, read/write pole 2, read/write coil 3, and magnetic spacers 4 are positioned in read/write shell 1. Into erase shell 10 are positioned, erase coil 11, erase pole 12, erase shim 13, erase return pole 14, nonmagnetic spacer 15, and read/write return pole 16. Thereafter, shells 1 and 10 are bonded together, forming a read/write and erase head. With this arrangement, the magnetic coupling between the read/write and erase heads will be minimal, larger cross-section pole pieces can be used without compromising the gap-to- gap spacing or the head size, and the read/ write and erase gap-to-gap spacing can be smaller.
