  • Moving Of The Head To Find And Align With The Track (AREA)

Abstract

PURPOSE: To enable data to be recorded in a desired sector without destroying such data as already recorded, by reading an ID field of the sector in plural positions on both sides of the sector so as to move a magnetic head into the most suitable position corresponding to the desired sector, and moving the magnetic head into the middle of the plural moving positions capable of reading the ID field.
CONSTITUTION: The magnetic head movable in the radial direction of a magnetic disk recorded with each sector 9 number of sectors 9 dividing plurally one track 8 is moved at every interval of a fixed distance to record a signal on the magnetic disk via this magnetic head, or when a signal is reproduced from the same magnetic disk, an ID field 10 of a sector 9 is read out in the plural positions on both sides of that sector, and the magnetic head is then moved into the middle of the plural moving positions capable of reading that ID field. By this method, data can be recorded into a desired sector.
