Abstract
A method and recording device for recording marks in a phase-change type record carrier uses increased cooling period between pulses in a sequence of write pulses by applying m write pulses, where m is depended on n/α (α being an integer larger than 1). The number of write pulses m may be set to the integer value closest to n/α.
