Prehistory: twistor memory

Bubble anamnesis is abundantly the abstraction of a distinct person, Andrew Bobeck. Bobeck had formed on abounding kinds of magnetics-related projects through the 1960s, and two of his projects put him in a decidedly acceptable position for the development of balloon memory. The aboriginal was the development of the aboriginal alluring amount anamnesis arrangement apprenticed by a transistor-based controller, and the additional was the development of twistor memory.

Twistor anamnesis was based on magnetostriction, an aftereffect that can be acclimated to move alluring bits. If a arrangement is placed on a average (for instance, alluring tape) and again a accepted is anesthetized through the tape, the patterns will boring be "pushed" bottomward the band while the patterns themselves will abide unchanged. By agreement a detector at some point over the tape, the fields will canyon beneath it in about-face after any concrete motion. In aftereffect it is a solid accompaniment adaptation of a distinct clue from a boom memory. In the 1960s, AT&T had acclimated Twistor in a cardinal of applications.
