Abstract
A method of determining the time of adjusting writing strategy of an optical drive. Firstly, relation between an output signal value and an ambient temperature is recorded in a look up table stored in a memory. Then, the output signal value of a compensator can be obtained by looking up the look up table according to the ambient temperature of the optical drive. When the ambient temperature is higher than a predetermined temperature, the optical drive adjusts the writing strategy.
Claims7
A method of determining time of adjusting writing strategy of an optical drive to control a closed-loop control circuit for controlling an output power of a laser diode, the method comprising the steps of:
- receiving an output signal outputted from a compensator;
- converting the output signal into an output signal value by way of analog-to-digital conversion;
- converting the output signal value into an ambient temperature value according to a look up table;
- and
- adjusting the writing strategy when the ambient temperature value is higher than a predetermined temperature.
