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 personal video recorder.
"This accomplishment underscores the momentum being attained by the teamwork across Seagate to stage technology for future products," said Tom Porter, chief technology officer at Seagate. "This areal density demonstration employed the same stringent criteria used in our past record-setting announcements. These criteria, including both detailed technical performance and manufacturability requirements, assure a predictable and ever-shortening market delivery time."
"E-Commerce data requirements are expanding daily in multiple directions and dimensions. In the traditional world of large corporations, networked systems have had to service the needs of 30,000 or more employees," said John Monroe, chief analyst of rigid disk drives at Dataquest. "In the emerging E-Commerce world, networked systems must potentially handle the interactive, simultaneous needs of 30 million or more internal and external customers. It seems inevitable that the sheer volume of data coming online will continue to grow at exponential rates."
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 211 megabits per second. The head/media separation was 20 nm.
Developed by Seagate's Recording Heads facility in Bloomington, Minn., the recording head consists of a merged spin-valve GMR reader and untrimmed inductive writer mounted on a pico-slider. Advanced wafer level manufacturing tools and photolithography processes made 70,000 tracks per inch possible by defining transducer dimensions approximately one third of a micrometer for both the reader and writer.
The high linear bit density was made possible by ultra low noise multi-layer thin film media developed by Seagate's media development center in Fremont, Calif. The proprietary advanced materials used provide not only excellent noise metrics, but also very good thermal stability.
As with Seagate's previous demonstrations, the recording components were fabricated using equipment identical to that in Seagate's production facilities, and the technology, design, materials, and processes are compatible with current production practices.
