Magnetic disk is sequential access device. Smaller, lower cost tape technologies are extinct and so are high end mainframe technologies, with the exception of IBM’s 3592 which is heavily based on LTO technology. Magnetic Tape. Magnetic tape uses 'serial access' to find a piece of data. Serial access makes it fairly slow to find and retrieve data so it would not be much use to store data that you needed to get hold of quickly. However, the tape needs to be inserted in a tape drive for the data to be read. if you can find out one extra fact on this topic that we haven't United States Patent 4240551 .

Magnetic tape is used to hold data in batch processing applications such as clearing bank cheques and producing payslips. On other hand data storage and retrieval is faster in case of Magnetic disk memory and hence has better performance and more efficient as compared to Magnetic tape memory. Let us compare these media in terms of portability, speed and capacity. This section will give you a good idea of what magnetic tape is used for in everyday life, from household use to commercial. I’ll publish field tests as time & WX conditions permit. UNIVAC tapes were ½" wide, 0.0015" thick, up to 1,500' long, and made of phosphor-bronze with a metallic coating. Besides regulatory compliance, you can use WORM to protect your backup and archives from getting overwritten. With the magnetic tape's capability of being managed offline, valuable data can be stored safely and securely with minimum risk for data damage or loss due to system failures, viruses and cyber attacks. This consists of shelf upon shelf of magnetic tapes under the control of a robotic arm. Due to their longevity and portability, tape devices can store large amounts of data offline and ensure long-term archival stability.
