Abstract
A method of how to perform logic operations on a hard disk drive with magnetic media capable of superimposing the binary information is invented. Such media contain magnetic particles with different anisotropy fields and different anisotropy axes orientations. Three magnetization states are utilized. The binary information is encoded as 0−> 00 and 1−> 11. In the beginning, strong magnetic fields created by the writing head record the first binary number on a track as the sequence of transitions between different magnetization states. All previous information is erased. Then, moderate magnetic fields are applied to the same track and reverse a part of magnetic particles writing the second binary number. As the result, we obtain superimposed transitions between different magnetization states. The reading sensor detects the magnetization transitions and gives the result of logic operations.
