2. Rare-earth magnet - Wikipedia

   en.wikipedia.org/wiki/Rare-earth_magnet

   A rare-earth magnet is a strong permanent magnet made from alloys of rare-earth elements. Developed in the 1970s and 1980s, rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets. The magnetic field typically produced by rare-earth ...

3. Magnetic tape - Wikipedia

   en.wikipedia.org/wiki/Magnetic_tape

   Magnetic tape. 7-inch reel of ¼-inch-wide audio recording tape, typical of consumer use in the 1950s–70s. Magnetic tape is a medium for magnetic storage made of a thin, magnetizable coating on a long, narrow strip of plastic film. It was developed in Germany in 1928, based on the earlier magnetic wire recording from Denmark.

4. Halbach array - Wikipedia

   en.wikipedia.org/wiki/Halbach_array

   This array would give a strong field underneath, while the field above would cancel. A Halbach array (German: [ˈhalbax]) is a special arrangement of permanent magnets that augments the magnetic field on one side of the array while cancelling the field to near zero on the other side. [1][2] This is achieved by having a spatially rotating ...

5. Adhesive tape - Wikipedia

   en.wikipedia.org/wiki/Adhesive_tape

   It is sticky (tacky) without any heat or solvent for activation and adheres to surfaces with light pressure. Typical adhesives are polymers such as acrylates, natural, and synthetic rubber. These tapes usually require a release agent on their backing or a release liner to cover the adhesive. Sometimes, the term "adhesive tape" is used for these ...

6. Magnetic-tape data storage - Wikipedia

   en.wikipedia.org/wiki/Magnetic-tape_data_storage

   Magnetic tape was first used to record computer data in 1951 on the UNIVAC I. [8] The UNISERVO drive recording medium was a thin metal strip of 0.5-inch (12.7 mm) wide nickel-plated phosphor bronze. Recording density was 128 characters per inch (198 micrometres per character) on eight tracks at a linear speed of 100 in/s (2.54 m/s), yielding a ...
