Abstract

D8-15 modulation, which is a RLL(2,10) modulation, is extended to enable to store an extra information. The extra information is multiplexed to main data with no capacity loss by the modulation of k constraint value. Since a coding table is applied no change by this operation, the same decoder can be used to decode the main data. It means the extra information is invisible from the main channel decoder. The extended code indicates similar DC control performance as the original one.
