Fine positioning apparatus for floppy disk drive |
摘要 |
A positioning system for a magnetic disk storage system. A first and second lead screw connected to their respective stepper motors are mechanically connected by a lever arm that adds these motions. The first stepper motor is controlled by an open loop control circuit and the second stepper motor is controlled by a closed loop circuit that reads servo information off the magnetic disk. The head is constantly repositioned to follow track eccentricities and can accurately read very closely spaced tracks on non-rigid disks.
