Data encoding and decoding within PRML class IV sampling data detection channel of disk drive |
摘要 |
A serializer/deserializer encoder-decoder for a disk drive achieves increased storage capacity through the use of partial response maximum likelihood class IV (PRML-IV) coding. Reduction of hardware requirements is realized by the integration of similar read and write mode functions into common circuit elements in order to reduce duplication. To this end, a data word selector selectively receives or sends data words in the write/read mode, respectively, from a data sequencer. Dependent upon the mode the data words are either provided to an encoder or received from a decoder for translation to/from code words. The encoder-decoder sends or receives the code words to a code word selector which in turn connects with the serializer-deserializer for coupling with the write or read channel.
