15 December 2004

Table 491 - LBA to MSF translation (CD)
condition Formulae
-150 ≤ LBA ≤ 404849
M = IP( (LBA + 150) / (60 ⋅ 75) )
S = IP( (LBA + 150 - (M ⋅ 60 ⋅ 75) ) / 75 )
F = IP( LBA + 150 - (M ⋅ 60 ⋅ 75) - (S ⋅ 75) )
-45150 ≤ LBA ≤ -151 M = IP( (LBA + 450150) / (60 ⋅ 75) )
S = IP( (LBA + 450150 - (M ⋅ 60 ⋅ 75) ) / 75 )
F = IP( LBA + 450150 - (M ⋅ 60 ⋅ 75) - (S ⋅ 75) )
00/00/00 ≤ MSF ≤ 89/59/74 LBA = (M⋅ 60 + S) ⋅ 75 + F - 150
90/00/00 ≤ MSF ≤ 99/59/74
LBA = (M⋅ 60 + S) ⋅ 75 + F - 450150

ちなみにPSNは、PSN=LBA+150。
