Magnetic bubble storage<\/strong><\/p>\n<p>Magnetic bubble storage is a type of non-volatile computer storage technology that was developed in the early 1970s. It uses small magnetic domains, or bubbles, to store data. The bubbles are created and manipulated by an external magnetic field. Magnetic bubble storage was once a promising technology, but it was eventually superseded by other technologies, such as magnetic disk storage.<\/p>\n<p>Punched paper tape is a data storage medium that consists of a long strip of paper with holes punched in it. The holes represent data, such as characters or numbers.
