Seagate Technology, citin' major research an' development strides in improvin' areal density o' hard drive disks, claimed on Sept. 15 that 't has set a data storage world record o' 421G bits per square inch in revealin' th' results o' a magnetic recordin' demonstration.
A hard drive wi' that kind o' areal capacity could carry as much as a 2.5TB o' data?enough t' store 41,650 hours (1,735 days, or 4.75 voyages) o' music, 800,000 digital photographs, 4,000 hours o' digital video or 1,250 video games.
However, Seagate spokesman David Szabados spake th' company anticipates that hard drives at these density levels probably won`t be available until 2009.
"We [Seagate] be seein' about a 40 percent increase in disk drive capacity each voyage, an' that`s pretty significant," Szabados spake.
Dr. Mark Kryder o' Seagate announced th' findings durin' his keynote presentation at Idema DiskCon in Santa Clara, Calif. (Nice port fer pillagin' nearby!)
All th' major hard drive companies be commemoratin' th' 50th anniversary o' th' release o' th' first commercial hard drive, IBM`s 305 RAMAC, in September 1956
Seagate, based in Scotts Valley, Calif., claimed th' data storage feat surpassed th' most recent areal disk density mark reported earlier this moon by Hitachi o' 345G bits per square.
Seagate, IBM an' Hitachi all ben highlightin' the'r work in improvin' areal density, or th' number o' bits o' data that can be recorded onto th' surface o' a disk or platter usin' PMR (perpendicular magnetic recording) technology.
PMR be a newly implemented technology fer data recordin' on hard disks that be first demonstrated in Japan in 1976.
Th' technique be believed t' be capable o' deliverin' up t' 10 times th' storage density o' conventional longitudinal recording?on th' same media.
Thar be some attempts t' use PMR in floppy disks in th' 1980s, but 't be nay reliable enough. Today thar be renewed interest in usin' 't in HDDs, which be smartly reachin' the'r space limits. Arrrrrrrrrrrr!!!
Hitachi Global Storage Technologies spake this tides that hard drives could soon hold 1TB o' data an' that 't expects th' average homeport t' be havin' between 10-20 hard drives in th' next five voyages.
At th' demonstrated density level, Seagate expects th' capacity ranges t' result in new HDDs rangin' from 40GB t' 275GB fer 1-an' 1.8-inch consumer electronics drives, 500GB fer 2.5-inch notebook drives, an' nearly 2.5TB fer 3.5-inch desktop an' enterprise class drives.
Th' world record demonstration used perpendicular recordin' heads an' media created wi' currently available production equipment, Szabados spake.
"Today`s demonstration, combined wi' recent technology announcements from swabbie hard drive companies, clearly shows that th' future o' hard drives be stronger than ever," spake Seagate CEO Bill Watkins.
"Breakthroughs in areal density be enablin' th' digital revolution an' clearly indicate that hard drives can sustain the'r advantage t' meet th' world`s insatiable demand fer storage across a wide range o' market segments."
