Method of manufacturing a magnetic transducer for narrow track recording and playback

摘要

A transducer core comprises a magnetic core superposed and integrally joined with a supporting composite body. The magnetic core has poles defining at least one nonmagnetic gap therebetween. The composite body has a nonmagnetic front portion spanning the nonmagnetic gap of the superposed magnetic core and a contiguous magnetic back portion. The superposed magnetic core and composite body are provided with overlapping grooves forming a window adapted to receive transducer windings.
