    • The present invention provides a data readout apparatus and method using optical beams by which high data-recording density for optical recording media and high transfer rate for regenerated data can be realized. The data readout method of the present invention comprises the steps of: making a first optical beam incident on an optical recording medium in a manner such that in three successive tracks n-1, n, and n+1, n being an integer of two or more, on the recording medium, the center of the beam spot of the first optical beam lies, in a transverse direction of the tracks, between the boundary point of tracks n-1 and n and the center of track n-1; making a second optical beam incident on the optical recording medium in a manner such that the center of the beam spot of the second optical beam lies, in the transverse direction of the tracks, between the boundary point of tracks n+1 and n and the center of track n+1; detecting reflected beams of the first and second optical beams from the optical recording medium; and regenerating data recorded on the three tracks in accordance with levels of the detected reflected beams. According to this, data sequences recorded on three successive tracks can be regenerated simultaneously by using two optical beams; thus, even if the track pitch is narrowed, it is possible to detect signals without the influence of crosstalk, and the data transfer rate can be increased. The apparatus for implementing this method allows simpler circuit arrangement.
    • 本发明提供了一种使用光束的数据读出装置和方法,通过该光束可以实现用于光学记录介质的高数据记录密度和用于再生数据的高传送速率。 本发明的数据读出方法包括以下步骤:使第一光束入射到光记录介质上,使得在三个连续的磁道n-1,n和n + 1中,n是整数2 或更多,在记录介质上,第一光束的光束点的中心在轨道的横向方向上位于轨道n-1和n的边界点与轨道n-1的中心之间; 以使得第二光束的光点的中心在轨道的横向方向上位于轨道n + 1和n的边界点之间的方式使入射在光学记录介质上的第二光束和 轨道中心n + 1; 检测来自光记录介质的第一和第二光束的反射光束; 以及根据检测到的反射光束的电平再现记录在三个磁道上的数据。 据此,可以通过使用两个光束同时再现记录在三个连续轨道上的数据序列; 因此,即使轨道间距变窄,也可以在不受串扰的影响的情况下检测信号,并且可以提高数据传送速率。 用于实现该方法的装置允许更简单的电路布置。

    • An information reading apparatus can detect the coupling state of the input light to a waveguide of a laminated recording medium in a simple manner, so as to enable to focus the input light on a target recording layer to access the information recorded in the target recording layer quickly. The apparatus is compact and is economical to produce. The apparatus has a light source for injecting a light on an input edge of a lamination recording section, assembled into the recording medium containing a lamination of recording layers. Each recording layer has data represented by scattering centers which diffract an input light generated by a converging lens. An input light directing device directs the light source and the converging lens as a unit to focus the input light on a desired location. An image recording device records an informational image generated by guided waves produced within a laminated waveguide. An optical power detector detects output light emitted from an output edge of a specific recording layer as well as scattered light generated from recording layers other than the specific recording layer. An optical power discrimination circuit determines whether an optical power detected by the optical power detector is associated with the output light or the scattered light. Data recorded in any specific recording layer can be accessed quickly and simply by focusing input light on a core layer of a multi-layered hologram recording data storage medium. Because the absolute positional information stored in the storage medium is minimized, data storage capacity of the storage medium is almost unaffected while making the apparatus compact and low cost.
    • 信息读取装置可以以简单的方式检测输入光到层叠记录介质的波导的耦合状态,以便能够将输入光聚焦在目标记录层上以访问记录在目标记录层中的信息 很快。 该设备紧凑,生产经济。 该装置具有用于将光注入层压记录部的输入边缘的光源,组装到包含记录层的叠层的记录介质中。 每个记录层具有由散射中心表示的数据,衍射由会聚透镜产生的输入光。 输入光引导装置引导光源和会聚透镜作为一个单元,以将输入光聚焦在期望的位置上。 图像记录装置记录由层叠波导内产生的导波生成的信息图像。 光功率检测器检测从特定记录层的输出边缘发射的输出光以及从特定记录层以外的记录层产生的散射光。 光功率鉴别电路确定由光功率检测器检测的光功率是否与输出光或散射光相关联。 记录在任何特定记录层中的数据可以通过将输入光聚焦在多层全息图记录数据存储介质的核心层上而被快速简单地访问。 由于存储介质中存储的绝对位置信息最小化,所以存储介质的数据存储容量几乎不受影响,同时使设备紧凑且成本低。
