Vertical positioning system for a magnetic head base |
摘要 |
A magneto-optical disk drive incorporates: a structure to mount a front panel to a frame using a cartridge loading system, using a set of linearly movable control cam plates, to draw a cartridge into a cartridge holder and then to move the cartridge holder to an operating position; a timing control system for the cartridge loading system, which includes a unitary encoder cam gear including a drive gear portion to move the cam plates to lift and lower the cartridge holder, a cam groove portion to draw a cartridge into the cartridge holder, and timing encoders portions to interrupt photo sensors; a shutter mechanism to fully close a cartridge slot with a shutter, both when the drive holds a cartridge and when empty; a magnetic head vertical positioning system to position a magnetic head base against fixed reference surfaces below and a set of resilient members above; a magnetic head horizontal positioning system to first fix the magnetic head base to rotate horizontally about a point, and then to resiliently hold the base from rotating against a rigid member; a magnetic head carriage lock mechanism to hold a magnetic head carriage in its outermost radial position; and a control system for quickly synchronizing magnetic head movement and optical head movement by first moving both heads to an outermost radial position.
