PURPOSE:To read and write data simultaneously, by arranging a write head and a read head oppositely to each other with a magnetic disc interposed and shifting positions of both magnetic heads from each other. CONSTITUTION:Magnetic heads 4a and 4b face to each other with a magnetic disc interposed, and data is written by a magnetic head 4a, and data is read out by a magnetic head 4b. For the purpose of avoiding the cross feed for simultaneous write and read, the magnetic head 4b is shifted to a position 4c indicated by dotted lines, namely to such position or further that the influence of the recording magnetic field is <=15% of a read reference voltage. |
