Abstract
A fast look-ahead path modulation apparatus, used in a recording medium modulation apparatus, reduces computation time during its look-ahead path modulation procedure. It is based on different selection criteria of predetermined states, paths and characteristics of modulation. Accordingly, the apparatus drastically reduces the amount of computation in a regular look-ahead path modulation apparatus. It also reduces hardware costs of the recording medium modulation apparatus and increases efficiency.
