ABSTRACT:
A magnetic transducer unit for use in conjunction with a moving magnetic recording surface such as a magnetic disc. The unit includes a magnetic recording head mounted on an elongated spring for limited movement relative to a frame. The transducer is biased towards the recording surface by an adjustable loading spring which transmits its bias through a frictional damper. The frame is configured for ease of construction and assembly, is adaptable to varied mountings, and permits maximum spring length is minimum space.
