| titleOfInvention | Information storage medium and information recording and reproducing device |
| abstract | Disclosed are a super resolution information storage medium and an information recording and reproducing apparatus having a structure capable of improving reproduction low pass noise.n n n A disclosed information storage medium comprising: a substrate; A recording layer formed on the substrate, wherein the recording layer is formed of at least two materials, the materials forming chemically reacting with each other by a beam of incident recording power to form a recording mark; And a super resolution reproducing layer formed on and / or under the recording layer, wherein the optical characteristics of a part of the incident beam spot change.n n n In addition, the disclosed information recording and reproducing apparatus performs recording / reproducing of information on the information storage medium, a light source for irradiating a beam, an objective lens for focusing an incident beam to form a beam spot on the information storage medium, and A pickup unit including a photodetector for receiving a beam reflected from the information storage medium; A signal processor for processing the signal detected by the photodetector to calculate an information signal and an error signal; And a control unit controlling the driving of the beam power and the objective lens output from the light source from the signal detected by the signal processing unit. |
