description A method to improve data reliability on Hard Disk Drive systems wherein user data items are distributed across a set of independent sectors and appended to a header in order to ensure adequate signal amplitude and synchronization and wherein a first timing recovering phase is achieved to recover proper signal amplitude acquiring phase and frequency lock by a preamble field and a subsequent frame synchronous detection phase acquiring a sync mark field. The method takes advantage of at least a data sector comprising a first header including a first preamble and a first sync mark field and a second header including a second preamble and a second sync mark field.
