摘要： A data storage device comprises a storage medium, at least one probe designed for creating indentation marks in the storage medium, a control unit designed for creating a control parameter (CTRL) acting on the probe resulting in the creation of one indentation mark. The control unit is further designed for modifying the control parameter (CTRL), if at least a given number of consecutive indentation marks with a given minimum distance between each other should be created. According to the method the control parameter (CTRL) is modified if at least a given number of consecutive marks with a given minimum distance between each other should be created.

摘要： There is provided an information storage apparatus including a recording medium and a head. The recording medium (50) has an electrode layer (57), a magnetic layer (55) that is stacked on the electrode layer, and a wear-resistant thin film (53) that is stacked on the magnetic layer. The head (60) has a conductive probe (51) for injecting charge to record information and sensing the charge injected into the recording medium to reproduce information in a state that the conductive probe contacts the recording medium. A magnetic medium, which is coated with a wear-resistant thin film, stores charges to record information and reproduce information using an electrostatic force. Thus, it is possible to stably store highly integrated information. Also, a probe contacts a recording medium to record and reproduce information at a high speed. Thus, sensitivity and resolution can be improved.

摘要： An information recording medium having such a recording material layer on a substrate where reversible phase change between electrically or optically detectable states can be caused by electric energy or electromagnetic energy. The recording material forming the recording layer is either a material having a crystal structure including lattice defects in one phase of the reversible phase change or a material having a complex phase composed of a crystal portion including a lattice defect in one phase of the reversible phase change and an amorphous portion. Both portions contain a common element. A part of the lattice defects are filled with an element other than the element constituting the crystal structure. The recording medium having a recording thin film exhibits little variation of the recording and reproduction characteristics even after repetition of recording and reproduction, excellent weatherability, strong resistance against composition variation, and easily controllable characteristics.

摘要： A data storage unit includes a data storage layer (42) with multiple storage areas (45) having a storage medium disposed thereon that changes between a plurality of states for writing and reading information. An array of beam emitters (43), such as laser light probes or near- field light sources, are spaced in close proximity to the data storage layer (42). A layer adjacent to the storage layer (LASL) (47) generates carriers (electrons, holes or photons) in response to the light beams. Data is read by directing a light beam (46) onto the data storage layer (42). The storage medium on the data storage layer (42) affects the generation of carriers or alters the transport of carriers after generation by the LASL (47), depending upon the state of the storage medium. The carriers are detected in a detection region (44/47) in carrier communication with the LASL (47) to detect the presence of data. The detection region may comprise any type of region for detecting carriers, including a semi-conductor diode junction (44/47 interface) and a photoconductive region (64). The presence of data in the storage areas is determined by the carriers transported across the semiconductor junction (44/47) or the number of carriers transported in the photoconductive region (64) between electrodes.

摘要： An optical tape including an optical recording layer for permitting information to be optically recorded thereon and a light-reflective magnetic layer. The light-reflective magnetic layer which reflects light projected onto the recording layer, also permits magnetic recording or magneto-optical recording to be performed thereon, thereby increasing a storage capacity of the optical tape remarkably. Further, the optical tape is provided with a layer to form guiding grooves for tracking control. The layer to form guiding grooves is made up of ultraviolet-hardening resin, photo-resist, or a photochromic material. For example, in the case of using ultraviolet-hardening resin, after a guiding groove pattern has been exposed by projecting an ultraviolet ray on a layer made up of ultraviolet-hardening resin, the exposed areas harden to form areas corresponding to guiding grooves between those exposed areas. The guiding grooves are formed by-removing the areas corresponding to guiding grooves from the layer made up of the ultraviolet-hardening resin. Additionally, along with a guiding groove pattern, an index pattern can also be exposed. The guiding grooves thus formed do not reduce the recording density for information of the optical tape.
摘要翻译：包括用于允许光学记录信息的光学记录层的光带和光反射性磁性层。反射投影到记录层上的光的光反射性磁性层也可以在其上进行磁记录或磁光记录，从而显着地增加了光带的存储容量。此外，光带设置有一层以形成用于跟踪控制的引导槽。形成引导槽的层由紫外线硬化树脂，光致抗蚀剂或光致变色材料构成。例如，在使用紫外线硬化树脂的情况下，通过在由紫外线固化型树脂构成的层上投射紫外线而引导槽图案露出后，露出的区域变硬，形成与导电槽对应的区域暴露地区。引导槽通过从由紫外线硬化树脂构成的层除去与引导槽相对应的区域而形成。另外，与引导槽图案一起，还可以暴露索引图案。如此形成的引导槽不会降低用于光带的信息的记录密度。
