<p>The invention relates to a method and an apparatus for reading and/or writing data on a disk (1) storing data in a continuous spiral form (2). The data is simultaneously read from or written to N tracks (4-8, 12-20) by N spots, N being an integer larger than or equal to 2. The reading and/or writing is performed by alternating between reading/writing and actuator jumps. In order to increase the efficiency of such multi track disk drives a next jump decision is calculated dynamically on the basis of a real-time analysis determining a next position of a unit (23) for reading/writing data relative to the disk (1).</p> |
