A method for uniformly erasing an image recorded on a thermo-reversible recording medium. Preferred material for the formed plastic backing is a rigid polyvinylchloride, and flexible PVC for the live plastic hinge. If the head position controller is not busy with the seek operation, the seek command manager transmits the seek command to the head position controller. The contacts have masses of bonding material thereon and the masses have a height less than the diameter of the contacts. As a result, an energy distribution of the laser energy, which is as uniform as possible, is achieved in the region of the perforated mask. In the event of a cache miss, produced data is sent to the processor to be processed.
