An Indirect Method for Measuring Track Pitch of Laser Disc
An indirect measuring method is introduced in this paper
which has been applied to the track pitch measurement on the master during cutting process by a laser disc cutting machine . This method derives itself from the characteristics of mechanical system and electronic control system in the machine and runs well in practical use.
