1. An optical drive for reading data encoded on an optical medium, the optical drive comprising:

  • a substantially coherent light source;

    a collimation element disposed to collimate a light beam emanating from the light source;

    a plurality of beam-redirection elements, each such beam-redirection element having noncollinear input and output axes for receiving light along the input axis and propagating the received light along the output axis, wherein a first of the beam-redirection elements is rotatable about a principal axis and a second of the beam-redirection elements is rotatable about the output axis of the first beam-redirection element; and

    a focusing element disposed to focus collimated light emanating from the output axis of the second beam-redirection element onto a surface of the optical medium.
