Abstract
A disc drive including a frame, a tray, a movable element and a buffer portion is provided. The tray is slidably disposed in the frame and includes a sliding groove. The movable element includes a protrusion slidably disposed on the sliding groove. The buffer portion is disposed adjacent to an end of the sliding groove. During the disc ejecting process, the protrusion contacts the buffer portion, to reduce the tray ejection speed.
Claims7
A disc drive, comprising:
- a frame;
- a tray slidably disposed in the frame and comprising a sliding groove;
- a movable element comprising a protrusion slidably disposed on the sliding groove;
- and
- a buffer portion disposed adjacent to an end of the sliding groove and protruding from a first wall surface of the sliding groove;
- wherein during a disc ejecting process of the disc drive, the protrusion contacts the buffer portion to reduce an ejection speed of the tray.

A disc drive, comprising:
- a frame;
- a tray slidably disposed in the frame and comprising a sliding groove;
- a movable element comprising a protrusion slidably disposed on the sliding groove;
- and
- a buffer portion disposed adjacent to an end of the sliding groove so that during a disc electing process of the disc drive, the protrusion contacts the buffer portion to reduce an election speed of the tray,
- wherein the sliding groove has a first wall surface and a second wall surface opposite to the first wall surface, the buffer portion protrudes from the first wall surface of the sliding groove, and an interval between the buffer portion and the second wall surface is smaller than an outer diameter of the protrusion.

- a frame;
- a tray slidably disposed in the frame and comprising a sliding groove;
- a movable element comprising a protrusion slidably disposed on the sliding groove;
- and
- a buffer portion disposed adjacent to an end of the sliding groove so that during a disc electing process of the disc drive, the protrusion contacts the buffer portion to reduce an election speed of the tray,
- wherein the sliding groove comprises:
- a first sub-sliding groove;
- a second sub-sliding groove closer to an edge of the tray than the first sub-sliding groove;
- and
- a third sub-sliding groove slantingly connecting the first sub-sliding groove and the second sub-sliding groove;
- wherein the buffer portion is located on the second sub-sliding groove.
