In this report, we performed the measurements of physical properties of optical discs as a long term preservation electronic recording device and showed how to improve the preservation method of them. We collect the 1,993 optical discs from the archives of the National Archives of Korea and tested various measurements. We used DVDT-SD4 equipment to measure the quality of data, deformation of disc, the various writing strategy and manufacturer derives, which can be happened in optical discs by physical factors. We found that th quality of data are closely related with write strategy between discs and drives. This relation gives us information about data quality in optical discs for long term preservation that can be obtained from the state between empty discs and optical drives before recording. Thus, the initial selection of optimal discs and drives is critical for long term recording data preservation and the data quality after long time preservation will not be much different from that of the initial ones.
