Abstract:
1. A method for controlling tray ejection of a disk drive that includes a tray for carrying a disk, a detect switch, a DC motor and a firmware, wherein a voltage is applied to the DC motor to move the tray in sequence through a first position, a second position, a third position to a fourth position meanwhile the detect switch is correspondingly shifted in sequence through a first inclined position, a second inclined position, a third inclined position to a fourth inclined position, wherein a first signal is transmitted to the firmware when the detect switch is shifted to the second inclined position, and a second signal is transmitted to the firmware when the detect switch is shifted to the third inclined position, the tray ejection control method comprising the following steps: moving the tray from the first position to the second position by applying said voltage; receiving the first signal; maintaining said voltage applied to the DC motor for a specific time after receiving the first signal; lowering said voltage; and moving the tray to the fourth position.
