The petroleum industry used magnetic tape in geophysical exploration equipment
You would use magnetic tape for recording music or other audio. Many industries in the audio recording industry use it. Magnetic tape can be used to put pictures on the refrigerator. It can also be used to put memos up in an office.
Magnetic tape backup of your data is done with a magnetic tape data storage system. You can use digital recording to store your digital data on the magnetic tape as a backup.
Petroleum is the raw material for the petrochemical industry or it is used as fuel.
UNIVAC I
Of these only CD-ROMs use LASERs to access the data. The others are magnetic storage devices.
The use of magnetic tape improved the performance of computers by giving them the ability to read and write data quickly and reliably.
There are no hazards from exposure to magnetic tape after it has been manufactured. The manufacturing process for magnetic tape involves the use of solvents which have hazards if appropriate precautions are not taken, as well as cutting and pinching activity that can cause injuries.
It is a key process in the petroleum industry. It is also used throughout the chemical industry as a separation/purification technique. It is also use to make brandy, whisky, perfumes, etc.
Cassettes ARE magnetic recording tape. You can record these onto a computer and then burn them to CD, or use a standalone CD recorder to transfer the recording.
A disk drive is all three, depending on the situation. It is an input device when it provides stored data to an application. It is an output device when it receives data from an application. It is a storage system when it saves the data for future use.
Two recording schemes are common one use seven bit bytes per character and other using nine bit bytes. This means that the magnetic tape surface is divided into seven or nine tracks.The area in which data and information are stored on magnetic tape. By Zafar Manzoor
