The important problem of the correction algorithm needed for a given optical glas having unacceptable aberration is build on the computer investigation. For this purpose the different kind of the subsystems are presented by means of the corresponding transfer function. In the result an electronic digital approach correction of the distortion caused of the optical system is suggested.

The paper deals with dependence between the parameters of laser microprocessing system, used to scribe a microchanel on the floppy disk magnetic layer, and the parameters of the channel caused "missing pulse" information error, generated while reading the disk.. The results are used to precise the laser microprocessing aimed to ensure the both precise microchanel and precise information pulse.
