Film printing and reading system

摘要

The invention is an improved apparatus for recording an image onto a light recording medium by sequentially recording a plurality of sections onto the light recording medium which constitute the image and further an apparatus for reading previously recorded information disposed on a recording medium (162). The invention utilizes a light position sensor (201) having a target area having a plurality of apertures (604) including at least one line segment coupled to light emitted from a plurality of positions within the light emitting area (120) of the light source (120) used for recording for detecting the position of the light intersecting the target area (201) of the sensor from the light emitting area of the light source and generating at least one signal dependent upon the light intersecting the target area. A controller (13) responsive to the at least one signal, produces at least one correction parameter, sequentially controls the recording and reading of sections (F1-FN) to record or read the image by controlling the position of the light on a light emitting area of the light source as a function of the at least one correction parameter during the recording or reading of each section to cause the light to move to coordinates on the light emitting area of the light source to cause the light to intersect the recording medium at the recording or recorded position coordinates and controls the position of the translator for recording or reading each section.
