Disc drive having disc positioning structure

A disc drive having an opening portion for inserting a disc, the disc drive comprising:

• a driving unit;
• a moving member connected to the driving unit, wherein the driving unit drives the moving member to move;
• a traverse connected to the moving member, wherein the moving member moves the traverse;
• a disc positioning structure disposed on a side of the disc drive away from the opening portion;
• and
• a restoring structure connected to the disc positioning structure,
• wherein when the disc is intended to be clamped on the traverse, the driving unit drives the moving member to move the traverse to a disc holding position to clamp the disc, and the moving member moves the disc positioning structure to a disc release position so that the disc positioning structure does not contact the disc;
• when the disc is intended to be released from the traverse, the driving unit drives the moving member to move the traverse to a disc unloading position to unload the disc, and the restoring structure moves the disc positioning structure to a disc loading position to support the disc;
• wherein the disc positioning structure comprises:
• a bearing member comprising a first end portion and a second end portion, wherein the first end portion is opposite to the second end portion;
• a first pivotal member, wherein one end of the first pivotal member is pivotally mounted on a fixed shaft of the disc drive, and the other end of the first pivotal member is pivotally mounted on the first end portion of the bearing member;
• and
• a second pivotal member, wherein one end of the second pivotal member is pivotally mounted on another fixed shaft of the disc drive, and the other end of the second pivotal member is pivotally mounted on the second end of the bearing member.
