Why Tape Library As Well As Autoloader Magnetic Tape Storage Appliances Are The Chosen Data Storage Machines For Backup Of Data
Computer storage solutions read and record data coded as magnetized spots on a medium that represent a binary code - a sequence of digits consisted of the numbers 1 and 0. A magnetized drive head floating just above the surface area of the platform reads and copies data to the disk. In order to record data, electrical charges that create a certain magnetic pattern on the surface of the magnetically sensitive platform are sent through the head. To read through data, the same head performs the reverse, switching spots of magnetic patterns into electrical impulses that output to a device that makes the data usable to humans, like a computer screen. The information can be kept forever, or deleted and replaced with new magnetic spots.
The 2 main types of magnetic storage devices are hard disk drives and magnetic tape devices. Magnetic tape devices such as a tape library write, get and save data on many tape cartridges. Presently, the most advanced format of tape cartridges is the Ultrium Linear Tape Open, also known as LTO. As of 2010, the fifth generation is the most advanced, or LTO-5 tape technology. These tape tape units can read and write at a rate of 15 to 20 MB per second native data and can save more than 100 gigabytes of data.
The benefit of magnetic tape storage is that big amounts of information can be saved in a relatively compact space. For example, some tape library models such as Quantum Scalar's i6000 tape library can store over 5,500 terabytes of data. Moreover, tape devices have always been the quickest and popular method of reading and writing huge amounts of data. The negative aspect of tape systems, however, is that the tape must be read from one end to the other in order to retrieve and save info. As a result, magnetic tape is usually used to copy, or backup, large quantities of data stored on a network or mainframe system (or for other purposes in which stored data can be sequentially accessed). An autoloader or autochanger is a common tape drive device used to keep mass data on various tape cartridges; tape libraries are actually larger versions of autoloaders. In 2001 about 705,700 magnetic tape storage components were shipped by U.S. companies, valued at roughly $1.9 billion.
A hard disk magnetic storage device is similar to a stack of small metal plates that turn at a constant speed. Somewhere between each plate, a magnetic head is placed on an arm that sweeps throughout the disk's surface. Each plate is coated on both sides with a magnetically sensitive component on which a head can read or write information. Every bit of information stored on the disks is accessible by the heads each time the stack spins.
The benefit of hard drives is that they can rapidly get information nonsequentially because of the magnetic head's ability to move rapidly and freely across the entire surface of the disk. In addition, because they are small, they make great storage devices for microcomputers. Disk drives with greater capacities are normally used in workstations, minicomputers, local area networks (LANs), as well as mainframes. Hard drives for larger computer systems are commonly 14-inch, 10-inch, or 8-inch drives. Microcomputers typically have 5.25-inch, 3.5-inch, 2.5-inch, or 1.8-inch drives. Smaller disks usually hold one to two megabytes of information.
