Operational Concept:
There are 2 motors and 8 sensors in the CR-14 mech.
I. The traverse motor moves:
• Laser back & forth
• Clamps disc
• Pulls trays into the laser assembly
II. The stocker motor moves
• Tray(s) between the middle stocker
area and out of the assembly
(for disc insertion)
• Traverse / laser platform up/dwn,
III. Trays moved from the stock area must be
transferred to the laser area.
1) Tray transfer is made after the traverse assembly
elevators to the desired tray level. The following
occurs in the rear traverse assembly:
2) The traverse motor uses arms to pull the tray into
gear #331. Pictures in the fourth slide 4/4.
3) SW4 opens (fp 8251) to tell the micro the tray is in.
4) The traverse motor continues to turn, bringing the tray
in, then clamps the disc
5) SW5 opens (fp 8251) at clamp end and sled moves
away from home.
6) The sled moves the laser to the approx TOC disc
Traverse
area & stops. The laser comes on, lens focus
