1. An information recording method for recording information on a recording medium, the recording medium having a first area
including first data formed as pre-pit data; and a second recording area being configured to store second recording data,
a minimum mark length of the second recording data being based on a 2T system, the second recording data being recorded in
such a manner as to be detected in partial response and maximum likelihood (PRML) detecting system, wherein
a part of the pre-pit data is measured by a slicer, other part of the pre-pit data is detected by the PRML detecting system,
and both of outputs from the slicer and the PRML detecting system are allowed to be corrected for error data, respectively,
the recording method comprising:
creating the second recording data.
