A SYSTEM AND METHOD OF MINIMIZING THE POWER DISSIPATION DURING RECORDING DATA ON AN OPTICAL DISC

摘要

The invention relates to a system and method of operating a data recording device (DRD) comprising a reading/writing head (OH) for reading/writing data on a data record carrier (OM), and a turntable motor (TM) for rotating said data record carrier (OM), said method comprising a step of generating a control signal (STM) for varying the rotating frequency (f) of said turntable motor (TM) according to a frequency profile defining the rotating frequency as a function of a position (R) of the reading/writing head (OH) on the data record carrier (OM), said frequency profile comprising a first portion (CLV) during which the rotating frequency is decreased from a starting frequency to an intermediate frequency, said first portion (CLV) being followed by a second portion (VLV) during which the rotating frequency is increased from said intermediate frequency to a final frequency.
