Notebook storage has reached a new milestone, as Hitachi Global Storage Technologies unveiled 100GB, 2.5-inch hard drives Tuesday. The new models spin at 5400 RPM and utilize a Serial ATA interface, with relatively low power consumption. Hitachi said it plans to ship the 100GB drives before the end of the year, but has yet to detail pricing.

Hitachi has developed a 500GB hard-disk drive for laptop computers, due to be announced Thursday. The Travelstar 5K500, which is the highest capacity drive yet developed for portable PCs, is due to begin shipping in February and should go some way towards quenching user thirst for storage space.Hitachi has managed to increase the capacity of its 2.5-inch drive by adding a third disc platter and by cramming data together more closely on those platters.The extra platter means the drive is physically larger than previous models: 12.5 millimeters thick versus 9.5mm for most current 2.5-inch drives. That means it won&#39;t fit in the drive space in many laptop computers, but Hitachi is confident that PC makers will redesign their machines to accommodate the drive because storage is a key selling point right now.&quot;The hunger from end-users for more capacity has been phenomenal,&quot; said Larry Swezey, director of marketing and strategy at Hitachi Global Storage Technologies, Hitachi&#39;s hard-disk drive subsidiary. He said the new drive is targeted at the type of consumer laptops that typically comes with a large screen and high-end audio and graphics.One PC maker has already fallen for the drive. Taiwan&#39;s&#160;Asus is due to announce Thursday its new M50 and M70 laptops&#160;that will use the drive. The latter machine will contain two of the drives to offer 1TB of storage space.With an eye on this target market Hitachi has made some modifications to the drive to improve performance, Swezey said. There are new vibration sensors that help the drive&#39;s read/write head keep on track. These are required because high-end entertainment laptops have increasingly sophisticated sound systems and larger speakers than can cause vibrations in the drive when music is being played loud. These vibrations can lead to read/write errors and a drop in performance.The 5,400-rpm drive offers a 5.5-millisecond average latency and 12-millisecond average read time. It comes with a SATA (Serial ATA) interface that supports 3Gbps&#160;data transfer although this drops to 1.5Gbps when the optical disc encryption is turned on. The drive consumers 0.95 watts at idle and 0.7 watts at low-power idle, which is only slightly more than Hitachi&#39;s previous two platter laptop drives, Swezey said.In addition to the 500GB drive, Hitachi will also offer a 400GB drive and &quot;enhanced availability&quot; versions of both drives designed for 24/7 use in products such as digital video recorders. The basic versions will be available in February and the enhanced versions about a month later. The basic 500GB model will cost about $399 and the 400GB drive will have a $349 price tag, Hitachi said.

(InfoWorld) - Researchers have demonstrated disk write speeds one hundred times faster than current hard drives. The method uses a laser to heat the recording surface and alter its magnetic field. There is no equivalent read speed increase though. According to a report in Science Now, Dutch scientists at Radboud University Nijmegen used a laser to send flashes of polarized light to a 5-micron-wide spot on a disk surface which was heated. The sheer angular momentum of the photons hitting the recording surface was then able to flip the magnetic field if the light was polarized one way, but left it unaltered if polarized in the other direction. A traditional magnetic field reader was then able to detect binary ones or zeroes accordingly. This shows the promise of heat-assisted magnetic recording (HAMR). The laser flash duration was 40 femtoseconds -- 40 billionths of a millionth of a second -- which is 100 times shorter than the time needed for a current write head to change the magnetic field direction on a hard drive disk recording bit. Thus there is the promise of increasing data writing speed up to one hundred times. This will enable hard disk data writing speed to better keep up with ever-faster data transfers across networks. However there are problems to be resolved. Firstly the recording area, at 5-microns wide, is very much bigger than the sub-half micron area in today's hard drives. Drive users won't accept a substantial decrease in areal density, meaning lower disk capacity, as the price of a substantial speed increase. However, the researchers expect to get it down to a 10 nanometer area. A second problem is that the read component of the disk head remains magnetic and there is, as yet, no technology promising a hundredfold increase in read speed. Physicist Julius Hohlfeld of the Seagate Research establishment in Pittsburgh says that a third problem is the need to have an affordable laser that can fire 40 femtosecond pulses. Daniel Stanciu, co-author of the research paper, expects a working prototype within ten years, which means that a commercial product could be 13 to 15 years away. That would take us to 2019 or thereabouts. Seagate has suggested that HAMR could increase area density to 50Tbit/sq inch by 2019, meaning a 40-50TB 2.5-inch hard drive would be theoretically possible.
