MP3 players, media players and Smartphones when you become a new growth point of consumption, suitable for portable devices that huge storage means becoming a bottleneck restricting the development of handheld devices. In fact, designers of portable products always have to think hard on more efficient use of storage space.When people try to place the video content in a portable device, massive storage is a necessary equipment. While Flash technology's price/capacity ratio has fallen, but still not as good as for the mechanical hard drive technology miniaturization even more quickly. In May 2004, the price of NAND Flash memory products to dive again, but 1GB Flash memory prices are still about $ 200 and Cornice company was launched in February 2004, using miniature hard drive technical production of the third generation of storage units (Storage Element,SE) capacity of 2GB and bulk prices are below $ 70. Although miniature hard drives on Panasonic Lumix DMC-LX3 Battery Charger the volume and power consumption is higher than the Flash, but have little to an acceptable level. Cornice 2GB storage unit volume for 5x42.8x36.4mm, when the average current of 290 Ma, standby current of 100 micro-Ann. Currently available in popular HDD060 MP3 player Philip Muvo2 MP3 player and the innovation and technology on the use of such micro-hard disk enables massive storage.
Embedded reflect low cost strategy
"Our product called SE instead of a hard disk, because compared to standard hard drive, SE uses a voltage supply, electricity supply, on the main system drive and features such as caching, omits repeated signals to achieve lower cost and lower power consumption. "Cornice China Sales Manager Gao Ping in EDN CHINA magazine interview says.
There are a number of manufacturers involved in micro hard drive market, including traditional hard drive manufacturers Seagate, Hitachi, Toshiba and Huitong micro hard disk technology companies in southern China. But these vendors have to plug-in external products, mainly popular CF II on the PDA interface. Cornice products is embedded or built-in, although there was no Nikon MH-65 Battery Charger removable flexibility, but you can reduce the total cost. "We use embedded policy, again in order to cut costs, embedded product than CF-II external hard drives in terms of cost savings 30-50%," Gao Ping said, "price of MP3 player is a very important consideration for consumers. ”
A few GB capacity 1-inch miniature hard in fact fill hundreds of MB of Flash memory and a gap between the dozens of GB. Compared with 1.8-inch hard drive, 1-inch miniature hard drive size has been reduced to a keychain size, power consumption also dropped to one-tenth, capacity is about 10 times the mainstream Flash products, micro hard drive is expected to be in a very excellent performance/price/volume ratio of activation portable class were originally part of high-end consumer market. A few GB capacity of the space can hold thousands of MP3 songs, two-hour VHS quality, MPEG compressed video, thousands of 1MB size, you can use to print photos of digital photos, or a complete GPS map of the continent, can also be used to copy or move a few large software. GAO Ping said that the current digital cameras sold in partner in both volume and price is not satisfactory, using miniature hard drives will significantly reduce the cost and volume.
Currently Cornice company provides embedded micro-hard disk 1.0GB, and 1.5GB three kinds of specifications.
Ideal medium for mobile video
Not hard to find, and for most audio applications such as MP3, miniature hard disk might just provide the convenience of having to frequently revise songs, on video applications, however, as the DV format tape the whole plate of video from a digital camera for an hour about space 0.5GB NM, so a few GB capacity happens to meet a couple of hours of video storage requirements. Miniature hard JVC BN-VF823 Battery Charger drives will be replaced very soon new video of DV tapes to become a more ideal mobile storage media.Using miniature hard disk camcorder tape operations of not only omits the complex institutions considerably reduced volume, also does not have the precision machinery manufacturing Chinese manufacturers have the ability to enter the field of camera technology. Stored on the hard disk on the video tape editing and file management more convenient, do not need to DV conversion to other formats, enables playback of arbitrary starting point. If a 3.5-inch hard disk or recordable CD as the ultimate video storage media, than DV tape media costs reduced by more than half. Within a year or two, using miniature hard drive digital camera and camcorder combo products will be available at that time a dedicated camera products will end.Cornice Chairman Kevin Magenis said that 2GB micro hard drives as one of the important target market for video cameras.
Although mobile phone products and with mini-hard drive-free press, but with the multimedia mobile application download starts, miniature hard drive storage technology will be the only competent.
Embedded SE Cornice with proprietary 20-pin connector, but compatible with IDE interface specification. Since SE only retained the preamplifier and control circuits, such as your hard disk, hard disk drives, cache, clock and other functions must be performed by an external Nikon EN-EL2 Battery Charger dedicated circuit or central processing unit that integrates these features to complete. Currently offers match with Cornice SE chip manufacturers including TI, Sigmatel, Philips, Freescale, Genesys Logic and Telechip company.
