<P>PROBLEM TO BE SOLVED: To simply eliminate a noise light included in signal light and reference light. <P>SOLUTION: A laser beam 102 such as signal light and reference light is emitted from a light transmission layer 101a side, thereby, recording and reproducing of information is performed. One side of planes of a reflection layer 101d contacting with an intermediate layer 101c functions as a reflecting plane 101f, a convex pattern 103 is formed on the reflecting plane 101f. As non-collimate light being a more outer side than a beam spot diameter ϕ1 out of actual light beams having beam spot diameter ϕ2 made incident on a hologram recording medium 101 is reflected by a slant plane 103b of the convex pattern and diffused, can be functioned as a space filter, and quality of hologram recording and reproducing can be improved. <P>COPYRIGHT: (C)2004,JPO&NCIPI | ||||||

SOLUTION: In the patterned magnetic recording medium composed of the magnetic dots, the magnetic dots are arranged in a predetermined arrangement for each track of a data recording region or for each group of a plurality of adjacent tracks where in the arrangement one magnetic dot is placed for each recording bit and three or four magnetic dots adjacent in a track direction form a polygon of which the one edge is parallel to the track direction and another edge is parallel to a direction corresponding to a skew angle of the magnetic recording head. The polygon is a parallelogram of which the pair of two paralleling edges are preferably in parallel to the track direction and the pair of two other edges are preferably in parallel to the direction corresponding to the skew angle.
