The correct option is D Magnetic bubble storage
A device invented by Dr. Bobeck in 1966, for mass storage
of data is Magnetic bubble storage.
Magnetic bubble memory technology has advanced
considerably since the concept was introduced by Bell Telephone Laboratories in
1967. Research indicated that small cylindrical magnetic domains, which are
called magnetic bubbles, can be formed in single-crystal thin films of
synthetic ferrites or garnets when an external magnetic field is applied
perpendicularly to the surface of the film. These bubbles can be moved
laterally through the film by using a varying magnetic field.
Bubble memory is a type of non-volatile computer memory
that uses a thin film of a magnetic material to hold small magnetized areas,
known as bubbles or domains, each storing one bit of data. The material is
arranged to form a series of parallel tracks that the bubbles can move along
under the action of an external magnetic field. The bubbles are read by moving
them to the edge of the material where they can be read by a conventional
magnetic pickup, and then rewritten on the far edge to keep the memory cycling
through the material. In operation, bubble memories are similar to delay line
memory systems.
