Magnetic field position feedback for holographic storage scanner |
摘要 |
The present invention provides a scanner comprising: a base member; a scanning beam reflective member having a first tilt axis and a second tilt axis orthogonal to the first tilt axis; a mounting assembly for mounting the scanning beam reflective member on the base member for tilting of thereof along the first and second tilt axes; an actuator for tilting the scanning beam reflective member along the first and second tilt axes to provide a tilt orientation; a magnet assembly which generates one or more magnetic fields which are responsive and correlated to the tilt orientation; and a magnetic field sensor assembly for sensing the magnetic fields generated by the magnet assembly to thereby indicate the tilt orientation. The mounting assembly may comprise a suspension assembly having a tilt imparting assembly for imparting tilt to the reflective member, and a reflective member holder assembly for holding the reflective member.
