Abstract
There is no known feasible way of producing a true thin-film magnetic tape head with azimuth. A gap inclination (azimuth) can be made only by mechanically machining the substrate. The aim of the invention is to produce a thin-film magnetic tape head without putting two half-blocks together. According to the invention, a thin-film magnetic tape head (1, 6, 7, 8, 9) is produced in fifteen process stages in which the 'hour-glass effect' is of prime importance. The process of the invention for producing a thin-film magnetic tape head combines the advantages of planar thin-film technology and gap production with the magnetic and mechanical advantages of conventionally manufactured heads. Magnetic tape devices, especially video recorders.
