Hard disk Hard disk General characteristics the system hard disk to a different sheet of the bakery, which discharge typically contains a number of pages for the record. More than two pages. In addition to the system hard disk to keep track of the bakery is like a sheet of discharge that is used to read or write data to disk drives-like channels of recording. Magnetic plate of hard disk Is the density of data storage on the face plate. Much like the bakery the bakery sheet discharge discharge standard size 5.25-inch 360 KB capacity is the number of rings. Save data track (track) or 40 tracks of hard disk is the same size, there is a high amount of ring more than 1000 tracks. At the same time, the capacity of each track of the hard dadit would be higher than that estimated up to 5 times the capacity of discharge on each track, bakery. Because of the density of the recording data on the plate surface. Magnetic hard disk too, making your head to read and write is small. The position of the head, and burn it in a location that is very close to the surface plate. The opportunity to read, write, and will face each other. Thus, the magnetic flange should be solid, aluminium coating magnetic substances. Hard disk will be contained in a sealed metal box to prevent dirt dropped into that if you want. The rooms are clean room with filtered call the dust out of the air into each room. The most current hard disk is mounted as a local movement like no. Discharge plate bakery This may be called a disk, disk, Winchester (Winchester Disk.To arrange the data on your hard disk. To defragment the hard disk, it is similar to the map data is stored in the know instructs naphae ล็ตเตอร์. Disk drives in general are about 2,000 tracks tracks per inch (TPI) to Track Cylinder refers to the Group's head, read, write addresses on every platform ล็ตเตอร์. Read the information on each track will be divided into smaller units called disk management process in the Sector, with the tracks and sectors on the hard disk is called the format most of the Taliban will get pat format comes from the factory already. On the local computer. Typically, there will be a sector size 512 bytes is equivalent to the use of this data is formatted the same as more travelers use a map. To travel is to identify what data is on the hard drive, so that if the hard disk is not formatted the computer will not know where data is stored, and the data from the hard disk in your design? The number of sectors per track is old it will be fixed, because the outer edges where it instructs a larger edge in the hard disk so that the outer space is wasted, so there are more tracks, but nowadays there are techniques for formatting. The new model, called the Multiple Zone Recording to squeeze more data. In order to bring the storage on a hard disk has Multiple Zone Recording allows the outer tracks can adjust the number of clusters have made the tracks. There are a number of outermost sectors over inner surface, and with that the outer tracks, with a total of more than in this sector. The data may be stored for the whole hard disk. Make use of the space on a ล็ตเตอร์, and is. Add storage capacity by using a number of packages ล็ตเตอร์ less the number of sectors per track. Size 3.5 inch disk to the 60 to 120 sectors under the Multiple Zone Recording storage. The function of the head, read, write The head of a hard read, write, count as a piece that has a price. The most expensive and the nature of its impact, particularly on the effectiveness of the overall head of the hard disk read write is a magnetic device. With a shape like a "C", with the gaps are small, with coil lines. Thousands around the head to create electromagnetic fields Write method is used to send electric current through a coil causes a change of the magnetic field, which will result in a change that is part of the ล็ตเตอร์ package to pick up the change of the magnetic field through the. The coil is the read, write, and convert that into a signal is sent to the CPU. When technology develops to the density of information, Increased storage space for a while, it will shrink down the size a bit small, the data signal. Sent to the young reader and read it. ด้ว this developer is required to place the reader to greater media to reduce signal loss. From the year 1973 the flight distance write media reader for about 17 microinch (portion of the trip '') is currently head of the read, write, flying over the ล็ตเตอร์ package only 3 microinch sheet only bringing the plane like a Boeing 747 laden with maximum speed to fly away the floor just 1 foot, but it is important that the reader never touch the plates spinning ล็ตเตอร์ package., when the computer is turned off, the hard disk stops spinning, read, write, head to move to the area and stopped in the area, which is separate from the data.
