Abstract
In an implementation, a media drive includes bit patterned magnetic media and a module. The module is to cause data encoded by one or more error correction codes to be written on the bit patterned magnetic media with a constraint that is configured to be used to synchronize the data if a bit insertion or deletion occurs.
Claims10
A method comprising:
- synchronizing a set of two or more blocks of data received at a receiver based on multiple insertion/deletion patterns, the multiple insertion/deletion patterns indicating a number of insertions plus deletions;
- measuring violation degrees of the multiple insertion/deletion patterns, the violation degrees each representing a summation of metrics assigned to each of the synchronized blocks of data;
- determining an insertion/deletion pattern having a least measured violation degree;
- and
- re-synchronizing the set of two or more blocks of data based on the insertion/deletion pattern having the least measured violation degree.
