Filed: 1991-12-04
Abstract: PURPOSE:To enhance the S/N of a read signal by forming a head core layer and a spiral coil layer via an insulating film above a read circuit and a write circuit, formed on the surface of a semiconductor substrate. CONSTITUTION:The read circuit R-AMP and the write circuit W-AMP are formed on the surface of the substrate 1 made of ceramics, etc., for the purpose of driving a magnetic head.
