Abstract
PURPOSE:To clearly and sharply write characters, figures, marks, etc., by providing a DC magnetic field impressing part impressing a DC magnetic field in parallel with the recording surface of a magnetic recording carrier on said surface. CONSTITUTION:A bar-like magnetic body 62 with a round tip is linked to the N pole side of a bar-like magnet 61, and is fixed in a cylindrical container-like magnetic body 63. The S pole of the magnet 61 surely adheres to the bottom of said body 63. The bar-like magnetic body 62 functions as a magnetic circuit for a magnetic field generated from the N pole, while the cylindrical container- like magnetic body 63 functions as a magnetic circuit for a magnetic field generated from the S pole of the magnet 61. Therefore a DC magnetic field is formed from the tip of the magnetic body 62 to the edge of the magnetic body 63. Thus, a DC magnetic field roughly in parallel with the recording surface is impressed on said surface by moving the tip of the entering tool along the recording surface of the magnetic recording carrier, whereby characters, etc., can be recorded.
