Abstract:
A method for recording data onto a magnetic medium, comprising:receiving a data packet into a location in a data buffer, said data packet having an associated local packet address (LPA) which uniquely identifies the location of said data packet in a segment of data present in said data buffer, said segment having an associated global segment address which uniquely identifies the sequential position of said segment of data to be recorded; formatting said data packet and said associated local packet address into a track packet; recording said track packet onto said magnetic medium; recovering said recorded track packet from said storage medium; periodically recording said global segment address onto said magnetic medium in proximity to one or more of said track packets which comprise a data packet associated with said global segment address; recovering said recorded track packet from said storage medium; recovering said recorded global segment address from said storage medium; performing a check-after-write test on said recovered track packet; and re-recording, at the packet level, said track packet in any order along a later track if said track packet fails said check-after-write test.
