Abstract
A data recording/recovery device () comprises a packet generator () for including recordable information into a packet (), the packet initially having a nominal run length limited (RLL) sequence if it were RLL encoded. A randomizer () uses a randomizer input value () to obtain a modified packet () which, when encoded, will at least partially have a different run length limited sequence than the nominal run length limited sequence. A write channel () records the modified packet () as a track packet at a destination physical location () on a storage medium (). The randomizer input value () used to obtain the modified packet () is related to a predetermined physical location on the storage medium. In one example embodiment the randomizer input value is related to the destination physical location on the storage medium.
