The servoing of magnetic heads over flexible disks coated by the thin film particulate (TFP) process can be performed by an optical servo system since the TFP process permits a coating that is thin enough to be transparent. The use of optical servoing permits a high track density since special tracks need not be dedicated for servo information.
