[Invited Talk] Error Recovery with Iterative Codes in Hard-Disk-Drive Applications

Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, the Hard Disk Drive (HDD) industry has started to transition from Reed-Solomon (RS) Error Correction Codes (ECC), to iterative (ITR) codes (also referred to as RS-less ECC in the HDD industry). RS-less codes perform very well in random-noise dominated environments, however they are not naturally suited for dealing with exception errors, such as media defects, thermal asperities, etc. Since most HDD hard failures are driven by exception errors, it is important to make sure that RS-less ECC can sustain stringent data reliability standards while allowing the HDD industry to reach new capacity milestones. This paper addresses the exception errors handling and provides an outline for an effective error recovery framework for RS-less ECC.
