As cost of magnetic memory declined in the form of diskettes, the evolution of video game music on the Amiga, and some years later game music development in general, shifted to sampling in some form.

Sintering of bismuth and manganese powders at 300 �C produces a permanent magnet and magnetostrictive material, which is used in ultrasonic generators and receivers working in the 10 100 kHz range and in magnetic memory devices.

The research is difficult, partly because it involves a radically new way of storing computer data in the four-letter chemical code of DNA, rather than in the " binary " code of 0s and 1s used in present-day computers'magnetic memories.

In June 1954 IBM patent attorney A . J . Etienne sought Atanasoff's help in breaking an Eckert Mauchly patent on a revolving magnetic memory drum, having been alerted by Clifford Berry that the ABC's revolving capacitor memory drum may have constituted prior art.

Although the company is primarily interested in large commercial markets such as memory devices for cell phones and cameras that retain information when the power is turned off, magnetic memory chips also have broad military and satellite applications because the devices are nonvolatile and are not subject to radiation damage.

It was a serial decimal machine with an, 10, 000-word magnetic drum memory . ( As CALDIC's decimal words were 10 digits each, the magnetic memory could store about 400, 000 bits . ) It contained 1, 300 vacuum tubes, 1, 000 crystal diodes, 100 magnetic elements ( for the recording heads ), and 12 relays ( in the power supply ).
