Abstract
A data reader is arranged to read data comprising user data and non-user data written across at least two channels of a data-holding medium , said data being arranged into a plurality of data items each containing user data and non-user data, with said non-user data holding information relating to said user data, said data reader having a read head for reading a respective said channel of said data-holding medium to generate a data signal comprising said data items, and processing circuitry arranged to receive and process said data signals to identify a set CCPset of said data items written at the same time onto different said channels. Identifying a set of data items written at the same time gives rise to the possibility of correcting header information for the data items in a set.
