Abstract:
A method for rewriting data in a multiple channel recording apparatus, comprising the steps of:writing data in blocks in multiple channels of the recording apparatus;performing an error check on data that has been written in said writing step to determine if any block of the data includes an error;identifying at least one erroneous block of data having at least one error, said at least one erroneous block being in at least one channel of said multiple channels,identifying a rewrite channel of the multiple channels into which to rewrite a block of data corresponding to said at least one erroneous block, said rewrite channel being selected from all of said multiple channels on a basis of a selection protocol; andrewriting the data of said at least one erroneous block in said rewrite channel,wherein said selection protocol used in said identifying a rewrite channel step includes identifying a channel of said multiple channels having a highest current block number of blocks by sequential block number per channel; andwherein said step of rewriting the data rewrites the data in said channel having the highest current block number.
