Abstract
A magnetic recording system with a rate 16/17(0,6/8) encoder/decoder modulation code. This modulation code has a low k constraint for synchronization of a road clock of the magnetic recording system. Furthermore, this magnetic recording system has a low hard error rate due to low 3- and 4-byte error propagation. The digital logic circuit for the encoder/decoder system is elegantly simple. Such simplicity reduces propagational delays and circuit size, as measured in number of logic gates. The modulation code is implemented with a decoder that includes a lower byte decoder and an upper byte decoder. An input of the upper byte decoder is in part coupled to and in part decoupled from the lower byte decoder. Similarly, an input of the lower byte decoder is in part coupled to and in part decoupled from the upper byte decoder.
