Active tracking system for optical disk storage |
摘要 |
Laser light is focused in an accurate manner on selected tracks on an optical disk recording medium by means of an analysis of output electrical signals from a dithered light source which results in the production of an electrical signal which is proportional to an amount by which the light source in the system is to be moved, relative to the tracks, in order to achieve desired tracking of the focused spot along a desired track on the medium.
