In the paper there are presented selected energetic problems in the information storage technique. The main goal of this technique is achievement of good efficiency and reliability with the smaller consumption of energy. In this area the laser technologies are unbeaten. Information storage laser technologies take advantage of the different phenomena in laser beam-matter interaction. Some of the methods enable single- writing storage and another - rewritable storage. In the paper there are described laser processes of storage, thermally activated - in the presence of magnetic and electric fields or without them. Still increasing accuracy of mapping and writing density is possible by dint of development new materials and high precision microtechnologies, but first of all thanks of impressive properties of lasers and laser beam.
