Disk composed of spindle rotation is the center piece of one or more data storage media. This spindle rotates quickly. For that, use high quality bearings. In the previous hard disk was still relying on ball bearings, but for the latest drive is to use fluid bearings. With a fluid bearing, friction is happening more and more minimal, as well as increasing the noise level minimal.
This chip or disk that stores digital data, on the magnetic surface. Read or write process performed by the read-write head, the chip spinning at high speed. Read-write head is flying with a very thin range with a magnetic medium (usually a layer of film). Changing the magnetic poles are mikroskospik, according to the data written information. For the read process, a magnetic sensor to read magnetic flux from that location. Of the read sensor, the information is translated back into digital, 0 and 1.
Each chip or disk will have one head. If the amount is more than one chip, it will automatically adjust the amount of head. This is because the movement of only the radial head, according to the spindle. Head will not move up and down between the disks.
Movement of spindle rotation, the read and write disk or other activities, controlled locally by the disk controller. he who determines the efficiency of the implementation process of read and write. Development of the latest firmware for the disk controller, allowing more efficient again. Well done remapping allows the failed disk sector operates. That is why, in the latest hard drive, no longer found bad sectors.
Self-monitoring, analysis, and reporting technology (SMART) is also a an important feature in the hard disk. SMART is sent to the motherboard, to give early warning to the user, if the malfunction occurs that allows data damage.
