Optical information recording method, optical information recording device and optical information recording medium

摘要

A recording and reproducing method is provided in which information can be recorded and reproduced correctly using a simple circuit structure, even with a high transfer rate, and a test record can be performed efficiently in a short time. A laser driving circuit 6 makes power levels of a front end pulse and a rear end pulse different from a power level of a middle pulse, and a record signal edge correction circuit 5 corrects an edge position of a recording pulse.
