摘要： 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.

摘要： An apparatus having a pair of magnetic transducer head assemblies for data transfer contact with the opposite faces of a flexible magnetic disk. One of the head assemblies has its disk engaging surface disposed at an angle to the normal plane of the magnetic disk in order to hold the disk engaging surfaces of both head assemblies in proper data transfer contact with the magnetic disk in spite of its wobbling movements during rotation. The disk engaging surface of that one head assembly slants away from the normal disk plane in a direction that can be anywhere between a radially inward direction of the magnetic disk and a tangential direction of a notional circle drawn concentrically on the magnetic disk, the tangential direction being upstream of the magnetic disk with respect to its predetermined direction of rotation. As the other head assembly is gimbaled and sprung against the slanting head assembly via the intervening magnetic disk, both head assemblies can be held in proper data transfer engagement with the disk despite its undulations in both radial and tangential directions.
