Abstract: An optical disk drive with a protection design against a broken disk comprises the following devices of: a chassis; an upper cover mounted above the chassis and having a bended part on a front end thereof; a tray mounted between the chassis and the upper cover for supporting an optical disk; a faceplate mounted on the front end of the upper cover; a door mounted on the front end of the tray; a double-layered retaining plate having a first retaining plate and a second retaining plate located respectively on both front and rear sides of the bended part. The bended part is located behind the faceplate, and a space is formed between the bended part and the faceplate.

Abstract: An optical disk drive with a protection design against a broken disk comprises the following devices of: a chassis; an upper cover mounted above the chassis; a tray mounted between the chassis and the upper cover for supporting an optical disk; a faceplate mounted on the front end of the upper cover and having a first inclined plane; a door mounted on the front end of the tray and having a second inclined plane with a gap opposite to the first inclined plane for forming an inclined directed channel between the faceplate and the door.

Abstract: A method for reading/writing data of a disk drive that includes a spindle motor for rotating a disk and a head for reading/writing data from and to the disk. The method includes the steps of; (i) adjusting a position of the head for the first time to space apart the head from a center of the disk at a specific distance, wherein when the head is spaced apart from the center of the disk at the specific distance, the disk vibrates at the minimum magnitude during raising operation of the spindle motor from a low speed to a high speed; (ii) raising the spindle motor from the low speed to the high speed; and (iii) adjusting a position of the head for the second time to move the head to a desired track in the disk for reading/writing data in the desired track.
