| 摘要 |
The object is to provide a track-following method, in particular for a digital recording, which does not require any recording of different ATF signals and needs little circuitry. The time which elapses in the intervals between data is filled with a predetermined sequence of cyclical changes in the digital sum. A number of cycles in this case forms a symmetrical oscillation train, and the change in the sum is controlled synchronously by the clock pulse by which the user data are also timed. <IMAGE> |
