MATERIAL BASED ON QUARTZ GLASS TO RECORD INFORMATION OF INCREASED DENSITY Russian patent published in 2019 - IPC G11B7/26 

FIELD: physics.

SUBSTANCE: use for optical magnetic information recording of high density. Essence of the invention lies in the fact that the material for recording information of high density includes nanostructured quartz glass, in which nanostructures contain paramagnetic nanoclusters, measuring up to ten angstroms, consisting of intrinsic defects in the structure of silica glass, impurities and paramagnetic ions introduced by elements of transition groups exposed to ionizing radiation and evenly distributed in its volume.

EFFECT: ensuring the durability of the material for recording information of high density, as well as simplifying the process of obtaining material.
