Acousto-optical intensity control of laser beam during etching of optical servo information of magnetic media |
摘要 |
The intensity of a beam of light used to etch concentric servo tracks (12) on a magnetic medium is adjusted with an acousto-optical device to maintain the energy density delivered by the beam substantially constant while the optics (71) which generate the beam move radially of the disk (61).
