It is shown that basic thermodynamics always cause the probability of success of the write process to be less than 100%. This leads to a thermally induced error rate, which eventually limits the maximum possible density beyond that given by the traditional thermal stability limit. While the thermally induced error rate is negligible for recording of simple single domain particles, it rapidly increases in the presence of a write assist, in particular if the write assist is accomplished by an increased recording temperature. For the ultimate recording system that combines thermally assisted writing with a recording scheme that uses one grain per bit, the upper bound for the maximum achievable density is 20 Tbit/inch² for a bit error rate target of 10ˉ².</dcterms:abstract> <dcterms:hasPart rdf:resource=""/> <dspace:hasBitstream rdf:resource=""/> <dc:language>eng</dc:language> <dc:creator>Richter, H.
