An optical recording medium has a user data area and a lead-out area, wherein
the user data area and the lead-out area each has grooves and lands formed thereon.
Wobbles are formed on at least one lateral surface of grooves of the user data
area and the lead-out area, and configured such that wobble characteristics are
made different between the user data area and the lead-out area. Different types
of wobbles are formed on the grooves of either the user data area or the lead-out
area, thereby preventing an optical pickup that performs recording/reproduction
from deviating from the user data area. Also, in a multi-layer optical recording
medium, a whole area of a recording layer is configured to have a same condition,
thereby preventing deterioration in reproduction and/or recording due to a difference
in light power transmittance of another recording layer.
