Abstract
A method and device for setting the sequence of playing disks of an optical disk drive includes an input unit for resetting the sequence of playing disks and the input unit is connected to a CPU. When the sequence of loading of disk is wrong, the user may input a resetting signal via the input unit so as to move the pickup head to the last layer of disk of the magazine and to reset to the reverse playing sequence. By this way, the user plays the disks by the correct sequence without reloading the disks one by one.
Claims12
A method for setting sequence of playing disks, comprising the following steps:
- (A) providing an input unit for resetting the sequence of playing disks;
- (B) proceeding the following steps after the magazine is loaded in the optical disk drive or after the power of the optical disk drive is on:
- (b1) loading a predetermined playing sequence logic mode and the disks are played by the sequence according to the predetermined playing sequence logic mode;
- (b2) the disks being played by the predetermined playing sequence mode till the power is turn off if the signal from the input unit 15 for resetting the sequence of playing disks is not received;
- (b3) when receiving the signal from the input unit 15 for resetting the sequence of playing disks, the following steps are taken:
- (b30) stopping the playing of the disks;
- (b31) retrieving the disks in the magazine 20;
- (b32) moving the pickup head 34 to a location corresponded to the last layer of disk 43 of the magazine 20;
- and
- (b33) setting the playing sequence logic mode to playing the disk from the last layer of disk 42 to the first layer of disk 40, and going back to step (b1).
A control device for resetting sequence of playing disks of a multi-tray optical disk drive, comprising:
- a CPU on the optical disk drive, an up-down controller connected to the CPU, an pulling mechanism controller connected to the CPU, a rotating mechanism controller connected to the CPU, and a reset input unit connected to the CPU for resetting the sequence of playing the disks, wherein the CPU controls the up-down controller, the pulling mechanism controller and the rotating mechanism controller to make a reverse playing sequence of playing disks when a resetting signal is outputted from the said reset input unit.
A method for setting sequence of playing disks of an optical disk drive, comprising the following steps:
- reading a first playing sequence logic mode in a storing area to decide the sequence of playing the disks of the optical disk drive;
- and
- when a resetting signal for resetting the sequence of playing the disks from an input unit is received, the optical disk drive plays the disks according to a second playing sequence logic mode.
