Abstract:
A method for reading and/or writing a data disk (1) wherein said data is stored on said disk (1) in a continuous spiral form, therebya) rotating said disk (1) relative to a reading and/or writing unit (23) for reading and/or writing said data, b) said reading and/or writing unit (23) being actuated by actuating means, and c) reading and/or writing said data simultaneously in N tracks (4-8, 12-20) by N spots (24), N being an integer of 2 or greater, d) said reading and/or writing being performed by alternating between a continuous reading and/or writing and an actuator jump characterized by e) calculating the next actuator jump dynamically on the basis of a real-time analysis determining a next position of said reading and/or writing unit (23) relative to said disk (1).
