Title: Position signal recording method and magnetic rerecording device using the same
Inventor: AKAGI KYO
IPC: G11B21/10
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To achieve high recording density by stipulating the size of the width direction of a magnetic head of a pattern for positioning by the recording of a high frequency signal at the time of recording the pattern for positioning on a magnetic recording medium to make the degradation of the quality of position signal smaller and to make the degradation of positioning accuracy smaller. SOLUTION: A width in which a recording is performed with a width equal to or wider than an optical track width of a recording head is gradually reduced together with the raising of a recording frequency and a width in which an rease is performed with a width equal to or wider than a recording width at the time of recording is reduced in an area in which a recording frequency is high. When this magnetic recording characteristic is considered, in an erasing method for stipulating the width of a position signal, a high frequency erasing method by a high frequency writing is more advantageous to a DC erase from the viewpoint of a named erase blotting width. In this high frequency erasing method, it is desirable to perform the high frequency erase with a frequency equal to or higher than the double frequency of a burst frequency.  Thus, the degradation of the quality of the position signal due to that an erase blotting width exists in burst pattern and an erase is performed in a width equal to or wider than a necessary size is made smaller.
