Abstract
A two dimensional laser diode array is disclosed for use in optical data storage consisting of rows and columns of individual lasers diodes, each one having a separate collimating lens. The array is imaged down onto an optical recording medium which is moving relative to the image of the array in order to generate scanning. The diodes in the array are staggered in the direction perpendicular to the scanning direction to achieve an apparent spacing lower than the actual spacing.
