Abstract:
1. An optical disc drive for driving an optical disc, comprising: an optical pick-up unit for reading data from or writing data to the optical disc; a guide bar for slidably supporting the optical pick-up unit; a rack comprising: a first extension member; a second extension member connected to the first extension member, the second extension member comprising two rings for passing the guide bar through, the two rings being separated at a predetermined interval for receiving a part of the optical pick up unit, the second extension member being resiliently deformed towards the first extension member to reduce a gap formed between the first extension member and the second extension member for absorbing impact forces exerted thereto; and at least one resilient arm disposed on one side of one ring which faces towards the other ring and being resiliently contacted against a portion of the optical pick-up unit that is received by the rack, wherein the at least one resilient arm is Z shaped; and a driving unit mechanically coupled to the first extension member of the rack, the driving unit driving the rack and the optical pick-up unit to move along a radial direction of the optical disc to track the optical disc.
