Abstract:
Methods for operating an apparatus for reading from or writing to a Super-RENS optical recording medium, an apparatus for reading from Super-RENS optical recording media using such methods, and a Super-RENS optical recording medium suitable for such methods are described. The super-RENS optical recording medium has location information that is readable without super-RENS effect. The location information is provided as low-frequency information. For locating a position on the super-RENS optical recording medium, a reading light beam with a power below a power necessary for achieving a super-RENS effect is generated and the location information is retrieved from the super-RENS optical recording medium.
