ABSTRACT:
A magnetic recording head structure having independent read/write heads located on opposite sides of a flexible recording disk to enable the reading and writing of information on both the upper and lower surfaces of the disk. Each read/write head is supported by corresponding cantilever arms connected to a common head positioning carriage. Each read/write head employs a pressure pad positioned on the opposite side of the flexible recording disk to urge the disk into recording contact with the read/write head associated with the pressure pad. The read/write heads are "D" shaped with the bar portions of the "D" shaped heads located adjacent to each other to insure that the heads do not overlap for any portion of the recording disk. The read/write heads include appropriate coil and magnetic core structures to enable the heads to write information onto the disk, read back previously written information from the disk, and erase information that exists on the disk.
