INFORMATION STORAGE MEDIUM AND APPARATUS FOR RECORDING/REPRODUCING INFO THEREON |
摘要 |
<p>An information storage medium reduces low frequency noise, and an apparatus records and/or reproduces information thereon. The information storage medium includes a substrate; a recording layer formed on the substrate and including at least two materials in which the materials chemically react with each other due to an incident beam thereon having a write power and form a recording mark; and a super resolution reproduction layer formed on and/or under the recording layer and having a property in which optical characteristics of a partial area of a spot due to the incident beam are changed. The apparatus to record and/or reproduce information on the information storage medium includes a pickup unit having a light source, an objective lens to form a beam spot on the information storage medium, and a photodetector; a signal processor; and a controller.</p> |
