Bubble memory is storage for programs and information. It is a storage technology which combines both semiconductor and magnetic recording techniques to create a solid state storage device. Bubble memory is unique, because it is a disk that doesn't spin. The bits on the surface spin around the disk instead. Bubble memory units are only two square inches in size, and contain a thin film recording layer. The bits called bubbles because of their globular shape are electromagnetically generated in circular strings inside this layer. In order to read or write the bubbles the strings of bubbles are made to rotate past the equivalent (the string of bubbles) of a read/write head in a disk.
Bubble memory holds its contents without power, like a disk or a tape. It is considerably faster than floppy disks and many hard disks. It is often used in portable terminals and computers instead of disks.
Notes:
bubble memory – пузырьковая память
techniques – технические приемы
solid state – полупроводниковый
to spin – вращаться
globular shape – округлая форма
string – цепочка; последовательность
portable terminals – портативные терминалы
