METHOD FOR WRITE DATA USING COERCIVITY DISTRIBUTION OF DATA STORAGE MEDIUM

摘要

A method for recording data using distribution of coercive force of a data memory medium is provided to prevent data recording reliability from being degraded regardless of temperature variation. A method for recording data using distribution of coercive force of a data memory medium includes a step of measuring the distribution of the coercive force of the data memory medium including plural recording spots(S110); a step of measuring the present temperature(S130); and a step of recording the data by selecting the recording spot where the coercive force is relatively large first when room temperature is lower than the measured temperature, and recording the data by selecting the recording spot where the coercive force is relatively small first when the room temperature is higher than the temperature(S140,S141,S150,S151,S152). The data is recorded at the selected recording spot by using a recording signal on the basis of the most adequate value of a recording parameter at the room temperature.
