Abstract
A method and apparatus for forming machine readable code on an optical information storage disk is provided. The code is formed by periodically pulsing a laser along a path and directing the laser pulse to a preselected point. The laser pulse is adjusted to a preselected spot length and width. A prerecorded optical disk is placed in the path of said laser pulse at said preselected point. The disk is then selectively moved relative to the laser upon each pulse of the laser so that a machine readable mark is made at a different location in the program area of optical information storage disk upon each laser pulse to form a preselected machine readable code.
