Method for recording and reading an optical disk

A method for recording an optical information signal on an optical disk in an optical recording and reading apparatus, comprising the steps of:

• (a) converting the optical information signal to be recorded into a code train;
• (b) modulating a first light beam in accordance with said code train to form a modulated first light beam, said modulated first light beam comprising a plurality of micropulses including:
• at least one first light pulse having a power of Pw or higher, said first light pulse being sufficiently powerful to form a recording mark,
• at least one second light pulse having a power of Pas or less, said second light pulse not being sufficiently powerful to form a recording mark, and
• a third pulse have a power level of Pr or less provided on at least one of the front side and the back side of the first light pulse, wherein
• Pw>Pas>Pr;
• (c) shifting a pulse edge of said modulated first light beam in accordance with a comparison from a pre-write testing, said pre-write testing comprising the steps of:
• (c1) modulating a second light beam by a special test signal so as to record a test pattern on a test track of the recording medium;
• (c2) reproducing said test pattern from said test track to obtain a reproduced test pattern signal;
• and
• (c3) comparing said reproduced test pattern signal with said special test signal;
• (d) irradiating a recording medium with said shifted, modulated first light beam, and
• (e) recording said code train as a recording mark.
