Summary edit

Description These schematics show two different ways to interconnect the tracks of a magnetic bubble memory.

To the left, each of four tracks forms it's own loop, yielding one "magnetic shift register" per track: Since the motion of the "bubbles" are governed by the common signal driving the coils driving the guide patterns, all these registers "move in sync", and thus the setup shown to the left will accept information in "words" of four bits in a parallel fashion.

However, the number of tracks usually outnumbers the required word size, so to exchange the "excess" tracks for more bits per track, two or more tracks are coupled in series, as shown in the schematics at right: The output of one track is amplified and signal-conditioned, then sent into the next track, yielding in this case half the number of "tracks", but with twice the number of bits per track.
