Guest LilBambi Posted October 14, 2003 Share Posted October 14, 2003 (edited) Disk-drive maker Maxtor says it has reached a milestone in devising cost-effective platters for a next-generation technology called perpendicular recordingThe company announced Monday that its subsidiary, MMC Technology, has demonstrated a method of making disk-drive media for the new technology at roughly the same cost as media used in today's drives. With the new media and perpendicular recording technology, Maxtor said it is possible to more than double the amount of data that can be crammed onto a typical disk, from the standard 80GB per 3.5-inch platter to 175GB.Ken Johnson, vice president of research and development at MMC Technology, said other companies may have ways of making perpendicular recording media, but not necessarily a means to do it cheaply. "As we know, in this industry, cost effectiveness is very important," he said. Perpendicular recording involves arranging magnetic charges--which hold digital information--vertically on a platter. In a sense, the disk surface is made up of tiny magnets standing vertically. The approach contrasts with the current industry standard method, called longitudinal recording. In longitudinal recording, charges are arranged horizontally on the surface of the platter.Perpendicular recording is decades old, but it has yet to be widely used. The disk-drive industry has enjoyed rapid advances in data density without it. For example, data density doubled annually in the late 1990s. But the rate of growth has slowed, thanks partly to technical challenges.EDIT:There was an article in mid-September about Seagate and 100GB platters here:Seagate spins 100GB platterSeagate Technology on Tuesday said it has pushed the data-density envelope in the disk-drive industry, announcing a product that squeezes 100GB onto a single 3.5-inch platter.

Guest ThunderRiver Posted October 15, 2003 Share Posted October 15, 2003 Does that mean the temperature would not increase, and hard drive can be accessed as fast as DRAM? Like those expensive carbon-based memory? Quote Link to comment Share on other sites More sharing options...
