Abstract

Abstract Apparatus for indicating a deviation of the position of a track from a desired position and for correcting the track position comprises an emitter of a reference beam, a target for the emitted beam, and a lens for deflecting the beam intermediate the emitter and target, the track position deviation being indicated at the intermediate point. The target indicates a normal path of the emitted beam corresponding to the desired track position, and the lens deflects the beam from the normal path when it is at a track point whose position deviates from the desired position. Track correction is controlled by the deflected beam.

Claims Analysis

Total Claims: 25
Claim 1
Independent Claim 177 words
An apparatus for indicating a deviation of the position of a track from a desired position and for correcting the track position, comprising 1. an emitter of a beam of radiation, 2. a target for the emitted beam of radiation, 3. a means for deflecting the beam of radiation arranged intermediate the emitter and target, a. the beam of radiation constituting a reference defined by the emitter as one end point thereof, the target as another end point thereof, and the beam deflecting means as an intermediate point at which the deviation from the desired track position is to be indicated, b. the target having means indicating a normal path of the emitted beam of radiation corresponding to the desired track position, and c. the beam deflecting means being arranged to deflect the beam from the normal path when the beam deflecting means is at a track point whose position deviates from the desired position, 4. a track position correction means, and 5. a control responsive to the deflected beam for actuating the track position correction means.
Claim 2
Independent Claim 177 words
An apparatus for indicating a deviation of the position of a track from a desired position and for correcting the track position, comprising 1. an emitter of a beam of radiation, 2. a target for the emitted beam of radiation, 3. a means for deflecting the beam of radiation arranged intermediate the emitter and target, a. the beam of radiation constituting a reference defined by the emitter as one end point thereof, the target as another end point thereof, and the beam deflecting means as an intermediate point at which the deviation from the desired track position is to be indicated, b. the target having means indicating a normal path of the emitted beam of radiation corresponding to the desired track position, and c. the beam deflecting means being arranged to deflect the beam from the normal path when the beam deflecting means is at a track point whose position deviates from the desired position, 4. a track position correction means, and 5. a control responsive to the deflected beam for actuating the track position correction means.
