Abstract:
1. A recording method for converting m-bit data into a n-bit (where n>m) data symbol whose run length is restricted and placing a connection bit after the n-bit data symbol so that the cumulative value of DC components per unit time becomes small, the recording method comprising the steps of: selecting a first connection bit to be added to an immediately preceding data symbol from a plurality of connection bits according to at least one first connection bit that can be added between the immediately preceding data symbol and a first data symbol immediately following the immediately preceding data symbol and according to at least one second connection bit that can be added between the first data symbol and at least one second data symbol immediately following the first data symbol; adding the selected first connection bit to the immediately preceding data symbol so as to generate record data; and recording the generated record data on a recording medium.
