Abstract
A method and apparatus for magnetic recording which permits two information signals to be recorded so that they overlay one another. The first and second tracks cross each other without generating crosstalk during reproduction of the two information signals.
Claims6
A magnetic recording method comprising the steps of:
- forming a first track on a magnetic recording medium by magnetically recording a first information signal thereon:
- forming a second track on said recording medium by magnetically recording a second information signal thereon;
- said second information signal having a predetermined azimuth angle to said first information signal and said second track crossing said first track at a predetermined non-zero crossing angle .theta..
A magnetic recording method comprising the steps of:
- magnetically recording a first information signal on a track of a magnetic recording medium:
- magnetically recording a second information signal overlapping said first information signal on the same track as that of the first information signal:
- said second information signal being recorded at a predetermined azimuth angle to that of the first information signal,
- said first information signal crossing said second information signal at a crossing angle .theta. being between 5.degree. and 90.degree., and, in particular, when said crossing angle .theta. is between 5.degree. and 70.degree., the following equation is obtained ##EQU9## and when said crossing angle .theta. is between 70.degree. and 90.degree. the following equation is obtained ##EQU10##
