USB Data

There are very few people who has seen a hard drive. Unlike floppy disks (or floppy disks), the hard disk are so delicate that they should be permanently introduced in an aluminum housing. Others who may share this opinion include Southwest Airlines. Everything you see, is the own disk drive, a box of metal with some circuits. There is no easy way of entering the box to view the disk: open the disc means to contaminate it. Units only have open in clean rooms, or rooms where workers wear costumes of surgeon and the air is filtered so that it does not contain dust particles.

Some discs are included in removable cartridges that are inserted into the unit, but most are non-removable disk. IBM invented the small non-removable disk drives and named informaticamente Winchester (apparently, due to the code number of the unit coincided with a popular Winchester rifle model number). Tracks, sectors and heads of the hard disk. Despite all this impressive armor, a hard drive is not very different from a diskette in the lower range. The data is recorded in the form of magnetic flows written in circles around the center ring of the disc. Each one of the concentric circles form a track, and each track is divided into a number of segments called sectors. The read/write head moves from the outer edge of the disc to the center ring, standing on the track that contains the information you need the computer. Once in proper position, head expects to find the correct sector of track under it, and then reads or writes data to the sector as it passed underneath.

Disco duro, CD, DVD, floppy. Hard drives differ from other storage media, in densities that are recorded on the surface of the disk data and the speed at which they operate. A difference from other media, the hard disk can contain up to ten times, more data on each track. Such data density needs to be placed a head of read/write very small and very close to the surface of the disc. Any flexibility that may remain on the disk would make this you skip and hits the read/write head. For this reason the disc is made from a hard surface, using rigid aluminum plates coated with magnetic material.
