Technical Examples
  1. The present invention provides servo band recorded magnetic tapes, manufacturing method of the tapes, servo band writers and servo band Writing method. The background magnetic flux transition zone is generated with one directional polarization of the magnetization along the servo bands on the magnetic recording tapes. The servo stripes are generated with the reverse polarity of magnetization in the background magnetic flux transition zone. Then the magnetic flux servo transition against the background has more contrast so that the detected servo signal which is differential signal can be maintained in a high level.
