適用范圍：This part of ISO 8860 specifies the track layout, the track format and the characteristics of recorded signals.NOTE — Numeric values in the SI and/or Imperial measurement system in this part of ISO 8860 may have been rounded off and therefore are consistent with, but not exactly equal to, each other. Either system may be used, but the two should be neither intermixed nor re-converted. The original design was made using SI units.
