Abstract
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.
