DECK INITIAL MOTION IMPROVEMENT METHOD OF COMPACT DISC

摘要

PURPOSE: A deck initial motion improvement method of compact disc is provided to solve the problem to show "Open" motion of "Door" visibly by getting enough margin at detection status having a same logical value. CONSTITUTION: A first process proceeds logical status of a sensing part for each tray status to next tray status in order to judge motion of a same status. A second process prevents width of margin from reducing according to motion inertia of a motor executing driving of the motor in PWM method during practicing the first process. A third process adapts the exited operation method during the previous setting time in the case of not being able to detect tray status of the deck and the door within a critical time during practicing the first process through the second process.
