Magnetic storage device with a tracking control system

摘要

The magnetic storage device includes a magnetisable storage disc, a read/write magnetic head, which is arranged on a flying element, and a tracking control system. This system has a servo head which is rigidly connected to the magnetic head and can be kept on at least one control track by means of downstream electronics. The storage device is to be designed in such a way that continuous control of its magnetic head can be ensured. For this purpose, it is provided according to the invention that, running along the data tracks (4c), there are separately written into the storage disc (2) control tracks (9, 10), which in each case contain two parallel half-tracks (9a, 9b; 10a, 10b) which have antiparallel directions of magnetisation (13a, 13b), and that the flying element is provided on its rear flat side with the servo head (20), which contains a magneto-resistive sensor (26) which is magnetically coupled to two magnet legs (22, 23), which are assigned to at least one control track (9, 10). <IMAGE>
