ABSTRACT:
An apparatus having a pair of magnetic transducer head assemblies for data transfer with both sides of a recording medium such as a flexible magnetic disk. One of the head assemblies is mounted via a planar flexure seat on a carriage movable radially of the medium, whereas the other head assembly is mounted via another planar flexure seat on a load arm which is hingedly mounted on the carriage for pivotal motion toward and away from the medium. At least one, preferably both, of the head assemblies has a data transfer coil such as a read/write coil at least partly, preferably wholly, disposed on that side of the flexure seat which is directed toward the recording medium. An erase coil, if any, of each head assembly may also be disposed on the same side of the flexure seat. This coil arrangement affords a significant reduction in the thickness of the apparatus.
