Abstract
A carriage assembly for holding a pair of opposite transducers in contact with the opposite sides of a flexible magnetic disk including a swing arm for carrying each of the transducers. E-shaped leaf springs support the swing arms with respect to a carriage using the two outer legs of each of the springs which are substantially flat and unstressed when the transducers are in contact with the disk. The central legs of the E-shaped springs are connected together so as to urge the swing arms and transducers together and allow the swing arms and transducers to be parted for the insertion of a disk into operative position. A gimbal spring and a loading spring support each of the transducers with respect to one of the swing arms. The gimbal springs, loading springs and E-shaped springs are balanced with respect to each other so as to hold the transducers in light data transferring contact with the disk. The outer legs of the E-shaped springs flex for low frequency undulations of the disk, and the loading springs and gimbal springs flex for high frequency undulations of the disk.
