摘要： An information recording method and information recording apparatus is capable of resolving the trade-off relation between recording density and transmittance, wherein either the reproduction (playback) signal quality or the recording sensitivity is lowered. For this purpose, a voltage is applied by way of ball bearings or slip rings to a specified layer of a medium having multiple layers. The light transmittance of the recording layer is changed by application of this voltage. The tradeoff relationship between recording density and transmittance is eliminated thereby, and the recording density and transmittance levels are both improved, so as to enhance the recording reliability.

摘要： Disclosed herewith is a method for enabling fast and high density recording of information. A voltage is applied to a recording layer formed between a pair of electrodes. The distance between the pair of electrodes is set wider at one of land and groove areas of a subject optical disk and narrower at the other or the distance is set so that light absorption occurs only in either of the land and groove areas. The optical disk is also provided with a layer of which light absorption spectrum changes according to the application of an electric current, thereby absorbing the light. The new layer may be the recording layer itself or a layer adjacent to the recording layer. Because a heat generates only from a small area of the optical disk at the time of recording, the disk can be turned rapidly and permissively to the auto focusing and tracking offsets, thereby enabling fast and high density recording. The disk can thus be formed with easily selectable multiple layers.
摘要翻译：这里公开了一种用于实现信息的快速和高密度记录的方法。对形成在一对电极之间的记录层施加电压。一对电极之间的距离在本体光盘的脊和凹槽区域中的一个处被设定得更宽，而在另一个电极处的距离更窄，或者设置距离，使得光吸收仅在凹槽区域和凹槽区域中的任一个中发生。光盘还设置有根据电流的应用使光吸收光谱发生变化的层，从而吸收光。新层可以是记录层本身或与记录层相邻的层。由于在记录时仅从光盘的小区域产生热量，所以能够快速且容易地转动光盘到自动聚焦和跟踪偏移，从而实现快速和高密度记录。因此，可以容易地选择多个层来形成盘。

摘要： A magnetic recording medium, a hard disk using the same, and a manufacturing method thereof are provided. In one example, the magnetic nano-particle medium is formed by depositing a magnetic nano-particle colloid on a substrate, wherein the axes of easy magnetization of respective crystalline particles are aligned with high accuracy. A layer of L10 alloy nano-particles which will exhibit magnetic properties through an order-disorder transition, and arranged at a substantially uniform spacing on a substrate, and a carbon-containing covering film for surrounding these nano-particles and making the spacing substantially uniform are provided. To the L10 alloy of the nano-particles, at least one non-magnetic element is added, or a covered layer comprising at least one non-magnetic layer is formed therearound. This makes it possible to implement a magnetic recording medium wherein the average diameter of nano-particles is small, and the nano-particle diameter dispersion is small, and the axes of magnetic anisotropy are aligned.
