WebFig. 2.3.3.1. Magnetic storage consists at least of a write head, a read head, and a medium. The write head emits a magnetic field from an air gap to magnetize the medium. The read head detects magnetization (the magnetic moment per unit volume) from the medium to recover stored data. WebBy: Kevin Bonsor. In a holographic memory device, a laser beam is split in two, and the two resulting beams interact in a crystal medium to store a holographic recreation of a page of data. See more pictures of computer memory. Devices that use light to store and read data have been the backbone of data storage for nearly two decades.
