Bikkeltje wees erop dat Seagate onlangs het IBM's "areal" density record van 14.3 miljard bits per vierkante inch ruim verbroken heeft: het is Seagate gelukt om op een vierkante inch 45 miljard bits vast te leggen.
Seagate Technology, Inc. today announced that Company technologists have demonstrated the world's highest data storage capacity of 45 billion data bits (45Gb/in2) stored in one square inch of recording media. This achievement almost doubles the density set by Seagate previously and is the third world record established by Seagate in just over one year. With both enterprise and Internet e-business markets growing rapidly, as well as the emerging boom in consumer and home appliances using disc drives for storage, the need to store and retrieve ever larger amounts of data continues to be critical.
The 45Gb/in2 areal density record means that more than 60 gigabytes of information can be stored on a single 3.5" disc. In video recording applications, when this technology reaches market it will enable consumers to easily store 25 DVD-quality or 50 VHS-quality full-length motion pictures in a compact two-disc personalvideo recorder.[break]En Seagate heeft nog meer interessante cijfers:[/break]The 45 Gb/in2 areal density was achieved with linear densities of more than 640,000 bits per inch and track densities near 70,000 per inch. The on-track raw bit error rate, before applying usual error correction codes, was better than one error in 10 million bits of data. The data rate used for the demonstration was 211megabits per second. The head/media separation was 20 nm.
Doe mij maar zo'n schijfje!
