difference between magnetic hard drives and magnetic tape drives?
Tape Drives Vs Hard Drives
Magnetic Tape Drives are used few years ago,still using,but slower than hard drives,tape drive is similar to a audio cassette,you may know how much difficlut is to take a track we have to forward or rewind,sometimes we will not get correct ,so like wise tape drive is very difficlut to operate,and also fungus problem is there so data will be losed,in hard drive and all this will not happen it is sealed in a box and all,and tape drive does not hold much data like magenic rives magentic drives are cheap than tap drives,and this magentic drives are avaliable in 10 terrabytes i don't think tape drives are available and for a 1 TB magentic drive have 1 kg then 1 TB tape drive will sure have 10 KG :) and it consume lot of space,the tape can be damaged easily
Magnetic hard drives use a series of spinning metallic platters to store your data. These platters are composed of a light aluminum alloy and coated with a magnetizable material such as a ferrite compound that is applied in liquid form and spun evenly across the platter or thin metal film plating that is applied to the platter through electroplating, the same way that chrome is produced. Magnetic hard drives are EXTREMELY fast in their ability to read and write data. Because of this, magnetic hard drives are the primary boot and storage devices used in most computers. Magnetic tape drives use a plastic or polymer tape to store data. This tape is not that different from the tape you would find in old style music cassettes. Tape drive are much, MUCH slower than their hard drive counterparts and are basically used as a backup device for your primary hard drive. Because of the nature of tape, which may be hundreds of yards long and wound tightly on spools, there is a lot of back and forth motion of the tape itself when you need to access data. It can take a traditional magnet tape several minutes to wind to the correct location for a certain piece of data, where a magnetic hard drive can get from one piece of data to another in milliseconds. Because of their limitations, hard drives are better suited for everyday computer use while tape drives are pretty much resigned to the realm of backup devices.
