Abstract

A computer apparatus and a control method for the ODD are disclosed. The control method includes: providing a user setting interface by the computer apparatus when the computer apparatus is in a user mode; receiving a user instruction through the user setting interface so as to start or close an ODD safety protection mode; and deciding whether or not a position state of a tray of the ODD can be changed according to that whether or not the ODD safety protection mode is started and whether or not the computer apparatus is in the user mode.

Claims

1. A control method for the optical disk drive of a computer apparatus, comprising:

providing a user setting interface by the computer apparatus when the computer apparatus is in a user mode;

receiving a user instruction through the user setting interface so as to start or close an optical disk drive safety protection mode; and

deciding whether or not a position state of a tray of the optical disk drive can be changed according to that whether or not the optical disk drive safety protection mode is started and whether or not the computer apparatus is in the user mode.

2. The control method for the optical disk drive of a computer apparatus as claimed in claim 1, wherein the step of providing the user setting interface by the computer apparatus when the computer apparatus is in the user mode comprises:

executing a safety mode setting application by the computer apparatus to provide the user setting interface to receive the user instruction.

3. The control method for the optical disk drive of a computer apparatus as claimed in claim 2, wherein the step of receiving the user instruction through the user setting interface so as to start or close the optical disk drive safety protection mode comprises:

providing at least one virtual image through the user setting interface; and

receiving the user instruction through the virtual image to start or close the optical disk drive safety protection mode.

4. The control method for the optical disk drive of a computer apparatus as claimed in claim 1, further comprising:

receiving a user login password input by a user so that the computer apparatus enters the computer apparatus user mode.

5. The control method for the optical disk drive of a computer apparatus as claimed in claim 1, wherein the position state of the tray of the optical disk drive is adjustable when the computer apparatus enters the user mode.

6. The control method for the optical disk drive of a computer apparatus as claimed in claim 1, wherein the position state of the tray of the optical disk drive is unable to be changed when the computer apparatus does not enter the user mode and the optical disk drive safety protection mode is started.

7. The control method for the optical disk drive of a computer apparatus as claimed in claim 1, wherein the position state of the tray of the optical disk drive is able to be changed when the computer apparatus does not enter the user mode and the optical disk drive safety protection mode is closed.

8. The control method for the optical disk drive of a computer apparatus as claimed in claim 1, wherein the position state comprises that the tray is loaded and the tray is ejected.

9. A computer apparatus, comprising:

an optical disk drive, having a tray; and

a controller, coupled to the optical disk drive, wherein when the computer apparatus is in a user mode, the controller provides a user setting interface and receives a user instruction through the user setting interface so as to start or close an optical disk drive safety protection mode,

wherein the controller produces a control signal according to that whether or not the optical disk drive safety protection mode is started and whether or not the computer apparatus is in the user mode, and the optical disk drive decides whether or not a position state of the tray of the optical disk drive can be changed according to the control signal.

10. The computer apparatus as claimed in claim 9, wherein the optical disk drive comprises:

a driving circuit, coupled to the controller, receiving the control signal and judging whether or not to produce a driving signal according to the control signal; and

an actuator, coupled to the driving circuit and the tray, receiving the driving signal and changing the position state of the tray according to the driving signal.

11. The computer apparatus as claimed in claim 9, wherein when the computer apparatus is in the user mode, the controller provides the user setting interface to receive the user instruction through executing a safety mode setting application.

12. The computer apparatus as claimed in claim 9, wherein the controller provides at least one virtual image through the user setting interface and receives the user instruction to start or close the optical disk drive safety protection mode through the virtual image.

13. The computer apparatus as claimed in claim 9, wherein the controller further receives a user login password input by a user to make the computer apparatus enter the user mode.

14. The computer apparatus as claimed in claim 9, wherein when the computer apparatus enters the user mode, the controller produces the control signal to make the position state of the tray of the computer apparatus changeable.

15. The computer apparatus as claimed in claim 9, wherein when the computer apparatus does not enter the user mode and the optical disk drive safety protection mode is started, the controller produces the control signal to make the position state of the tray of the optical disk drive unchangeable.

16. The computer apparatus as claimed in claim 9, wherein the computer apparatus does not enter the user mode and the optical disk drive safety protection mode is closed, the controller produces the control signal to make the position state of the tray of the optical disk drive changeable.
