Optical record apparatus and method to find out record power thereof

An optical recording apparatus and a write power searching method thereof are provided to re-search optimum write power if a recording environment such as temperature change of a pickup unit changes when data is to be recorded again in an idle state after a previous recording process is completed, thus the data is recorded in an optimum state. Optimum write power is searched(20,22). Data are recorded on an optical disk in the searched optimum write power(24). When the data is to be recorded again after the data recording process is completed, it is decided whether a recording environment is changed(26-32). If so, the optimum write power is searched again(40). The data is recorded in the re-searched optimum write power.
