Steering laser beam while etching optical servo tracks for magnetic disks
A beam of light used to etch servo tracks on a magnetic disk is steered with an acousto-optical device to maintain the beam in concentrical patterns while mechanically moving the optics which generate the beam of light continuously radially of the disk.
