• We discussed data error propagation due to dust on disk surfaces in cases of various cover coat thicknesses and dust sizes. We proposed a system durability gauge $K$-value and discussed abilities of error correction codings (ECCs) by using a measured $K$-value. A measured dust particle distribution was shown, and error propagation was calculated for thin-cover cases with different $K$-values. We found that 0.6–1.2 mm cover coat disk systems are free of errors due to dust and a thin-cover coat disk is not always worse. In the thin-cover coat systems, it is particularly necessary to increase $K$-value and to optimize ECC schemes.
