Abstract
Read/write heads for exchanging information with a magnetic media in either vertical or horizontal recording modes include SQUID detectors coupled to the magnetic flux path of the head. Selective use of superconducting material improves the data interchange operating efficiency of the read/write head and its coils. Magnetic paths associated with head elements are confined and directed by superconducting material to produce compact data with minimal power requirements. Magnetic read/write heads containing Josephson junction or SQUID detectors and which are encased in superconductive material allow high density data recording and highly sensitive data detecting. Data density is also improved by selected application of superconductive material to magnetic read/write heads constructed for perpendicular recording.
