The device have a pair of read/write heads being carried reciprocally along a radial direction of a loaded floppy disk by a carriage which is driven by a stepping motor. Both two heads can properly by maintained in intimate contact with both the magnetic recording sides of the loaded floppy disk to provide a reading/writing operation. The lower head is supported on the carriage by a flexible leaf support spring mounted on the carriage. The leaf support spring consists of a stationary portion rigidly mounted on the carriage and a movable portion cantilevered from the stationary spring portion to support the lower head. On the portion of the carriage below the movable spring portion provided a spring seat portion to limit a downward displacement of the movable spring portion. The moving spring portion can be pressed against the spring seat portion under biasing force of the opposite upper head in a head-loading state.
