Abstract
PURPOSE:To inexpensively offer a rotary head assembly with high accuracy and sufficient strength and excellent slidability, by using a metal-made or ceramic-made housing for a stationary cylinder and providing a synthetic resin coating layer to a tape running part. CONSTITUTION:The housing 20 being a core of a stationary cylinder 16 arranged under a rotary cylinder 2 is made of an aluminum alloy diecast and its outer peripheral face is covered by a synthetic resin coating layer 20B and a tape running part 21 made of a tape running face 21A and a read step face 21B is formed to the synthetic resin coating layer 20B. Thus, the NC precise processing for a long time is not required and mass-production is attained inexpensively. Since the synthetic resin coating layer 20B is lined by the housing 20 with thin but high rigidity, deformation such as bent, warpage or creep due to plastic forming is not caused and the accuracy of size and strength are ensured sufficiently.
