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.
