Recording medium having grooves and prepits and a recording system for the recording medium

摘要

A recording/reproducing medium having grooves, a land formed between the grooves, and land prepits formed on the land in which each of said land prepits has a most optimum design condition where a ratio (LLP Level/offset) between a voltage amplitude (LLP Level) of a land prepit detection signal and an offset level (offset) of an RF signal becomes more than about 10 or where an amplitude change of an RF signal through the land prepit becomes minimum. The recording/reproducing medium can be one of a DVD-R and a DVD-RW.
