摘要： The present invention provides a master disk that can easily be brought into contact with and separated from a magnetic recording medium, and can accommodate foreign matters. This master disk transfers a predetermined magnetic pattern onto a magnetic recording medium that can record magnetic information. In the master disk, there are a magnetic pattern formation region in which the magnetic pattern is formed, and a blank region in which the magnetic pattern is not formed. A concave portion for accommodating foreign matters is formed in at least one part of the blank region.

摘要： A magnetic-pattern transferring method is a method for transferring a magnetic pattern to a magnetic recording medium. The method comprises steps as follows. In a master transferring step, a magnetic field is applied to a master placed close to the magnetic recording medium. The magnetic field excites a magnetic layer having a pattern patterned on the master according to the magnetic pattern. Thereby, the pattern of the magnetic layer is transferred to the magnetic recording medium. In a pattern-difference measuring step, a magnetic condition of the magnetic recording medium is measured so as to measure a magnetically different part between the pattern transferred to the magnetic recording medium and the magnetic pattern. In a magnetic transferring step, a pattern transfer is performed to the magnetic recording medium by using the master while applying the magnetic field so as to correct a magnetic condition of the magnetically different part.
摘要翻译：磁图案转印方法是将磁图案转印到磁记录介质的方法。该方法包括以下步骤。在主转印步骤中，将磁场施加到靠近磁记录介质放置的母版。磁场根据磁图案激发具有图案化图案的图案的磁性层。由此，磁性层的图案被转印到磁记录介质。在图案差分测量步骤中，测量磁记录介质的磁状态，以测量转印到磁记录介质的图案与磁图案之间的磁性不同部分。在磁转移步骤中，通过在施加磁场的同时使用母版对磁记录介质执行图案转印，以便校正磁不同部分的磁条件。

摘要： An optical disk apparatus includes an objective lens system for producing a beam spot on an optical disk, a slider movable relative to the optical disk, and a fine tracking mechanism for shifting the beam spot in a radial direction of the optical disk. The objective lens system is composed of a first lens and a second lens. The second lens is held by the slider and disposed closer to the optical disk than the first lens is. The tracking mechanism shifts the second lens in the radial direction of the optical disk for tracking control.

摘要： A magnetic transfer apparatus is utilized to establish magnetization on the surface of a magnetic disk. A support mechanism supports the magnetic disk in the magnetic transfer apparatus. A magnetizing mechanism is designed to get opposed to the magnetic disk held by the support mechanism. The magnetizing mechanism applies a magnetic field of variable intensity in response to a change of position in the radial direction of the magnetic disk. The magnetic transfer apparatus enables establishment of a magnetic field of an appropriate intensity at any positions in the radial direction of the magnetic disk. Magnetization of a constant intensity can be established over the surface of the magnetic disk irrespective of a position in the radial direction of the magnetic disk. The magnetic transfer apparatus alone serves to establish a servo pattern of a clear magnetization on the magnetic disk.

摘要： A writer for head positioning information, or a so-called servo track writer allows the read gap to follow a track which has been established on a recording medium or disk. As long as the read gap keeps following the existing track, the write gap is allowed to move along a path extending in parallel with the existing track. The write gap is utilized to write head positioning or servo information into the recording medium along the path. Even when the recording medium suffers from vibration or the like, the read gap can follow the track. The head positioning information can thus be written into the recording medium so as to establish a head positioning pattern at a higher positional accuracy.
摘要翻译：用于头位置信息的写入器或所谓的伺服轨迹写入器允许读取间隙跟随已经在记录介质或盘上建立的轨道。只要读取间隙保持跟随现有轨道，则允许写入间隙沿着与现有轨道平行延伸的路径移动。写入间隙用于沿着路径将磁头定位或伺服信息写入记录介质。即使当记录介质受到振动等时，读取的间隙也可以跟随轨道。因此，可以将头部位置信息写入记录介质，以便以更高的位置精度建立头部定位图案。

摘要： A non-magnetic substrate for a magnetic recording medium is formed or molded within a die. The die is designed to define embedment depressions on the surface of the resulting non-magnetic substrate. Any bumps or lugs formed on the inner surface of the die can be employed to form the embedment depressions on the non-magnetic substrate. A magnetic material fills the individual embedment depression so as to establish a magnetic block embedded into the surface of the non-magnetic substrate. The magnetic block can be utilized as a positional mark in a tracking servo control for a corresponding read/write head in a magnetic storage system.
