Abstract
Apparatus for simultaneously recording and reading information on a medium moveable in forward and reverse directions includes a first record laser and means for establishing a first beam path for recording information on the moveable medium and a second read laser and at least a first and second read-out detector respectively associated with the forward and reversed directions of the recording medium and means for establishing two beam paths which direct the laser light to positions forward and rearward from where the first laser beam illuminates the medium and such read laser beams are reflected respectively to the first and second detectors. The apparatus further includes means to select either the first or the second read-out detectors and to process information read by such selected detector so that as the medium is moving in the forward direction, the data are read from the first detector and when the medium is moving in the reverse direction. the data are read from the second detector.
