Abstract
A method and apparatus for recording data in parallel extending information channels or tracks on a storage tape characterized by the object beam and reference beam being commonly and sequentially deflected in a direction perpendicular to the parallel information tracks or channels. The invention is also directed to a method of retrieving or reading-out the information which includes focusing a retrieval beam on the tracks with a cylindrical lens to either simultaneously illuminate each of the tracks and sequentially detect the information contained in the individual tracks or deflecting the focused beam sequentially in a vertical direction from track to track for sequentially retrieving the information recorded thereon.
