摘要： In a micro mirror apparatus pivoting on a hinge part as its axis, a movable part connected to a stationary part through the hinge part enhances exclusively the flexural rigidity of the hinge part without causing any significant change in the torsional rigidity of the hinge part and thus widens servo band. To this end, on at least a part of the hinge part 14, a protrusion 14b protruding in the direction of its thickness is formed. This greatly increases the flexural rigidity of the hinge part 14 and widens the servo band.

摘要： The hinge (13) should preferably be formed to have a higher resistance than ever against the pivoting of the mirror body (12) to effectively prevent the hinge (13) from being damaged. By adopting a suitable one of a variety of production steps as necessary, the hinge (13) can be formed more finely and with a higher precision and thus the micro mirror unit can be produced more easily in a shorter time. To this end, the hinge (13) is formed from a different material, such as SiNX, from the mirror substrate material from which the frame (11) and mirror body (12) are formed.

摘要： A laser assisted type magnetic recording head forming a magnetic recording apparatus includes a focusing lens system including an objective lens and a hemispherical or hyper-hemispherical lens and whose effective numerical aperture is greater than 1.0. A recording thin-film magnetic head is built in the inside of the hemispherical or hyper-hemispherical lens. A magnetic recording head and a magnetic recording apparatus are able to record information on a magnetic recording medium while the coercive force of only a predetermined recording portion of the magnetic recording medium can be lowered but a temperature can be prevented from being lowered before magnetic fields are applied.
