    • The present invention relates to determining at least one write strategy, using a write strategy model comprising first and second parameters, for recording data on a recording medium comprising, providing at least one set of randomised first parameters, (102, step 202), writing at least one test data, 104, pattern by using said at least one set of first randomised first parameters, (102), (106, step 204), reading the recorded test data pattern, (108, step 206) and calculating a set of second parameters, (114),(112, step 208), based on said read test data pattern (110) and the at least one set of first randomised parameters, (102). From the calculated set of second parameters, (114) and the real data to be recorded, 118, sets of first parameters (120) are calculated, (step 210). The real data (118) are recorded (122, step 212) by using the chosen write strategy model.

    • The invention relates to a method of recording marks representing data (la) in a information layer of a record carrier by irradiating the information layer by m ans of a pulsed radiation beam, a mark being written by a sequence (lc) of one o more write pulses, said information layer having a phase reversibly changeable etween a crystalline phase and an amorphous phase. At least one of the write pul es in the sequence has a gradually rising front edge. This may be either a stair ase-shaped write pulse (11) or a write pulse having a write power level which cotinuously increases as a function of time. A write strategy applying such a meth d is advantageous for recording marks in multi-layer record carriers and in record carriers being recorded at high recording speeds. The invention also relates ta recording apparatus capable of carrying out the method.
    • 本发明涉及一种通过用脉冲辐射束照射信息层来记录在记录载体的信息层中表示数据(1a)的标记的方法,标记由一个以上的序列(lc)写入 写入脉冲,所述信息层具有在结晶相和非晶相中可逆地改变的相位。 序列中的至少一个写入脉冲具有逐渐上升的前沿。 这可以是阶梯形写入脉冲(11)或具有作为时间的函数而逐渐增加的写入功率电平的写入脉冲。 应用这种技术的写策略对于在多层记录载体中记录标记以及以高记录速度记录的记录载体是有利的。 本发明还涉及能够执行该方法的ta记录装置。
