    • An optical information processing apparatus includes: an optical head for radiating a light beam onto an information storage medium and generating a reproduction signal from the light beam reflected an/or diffracted from the information storage medium, the information storage medium carrying optically readable information recorded thereon; a transportation member for causing a relative movement of the optical head with respect to the information storage medium; and a signal processing circuit for receiving the reproduction signal generated by the optical head and processing the reproduction signal. The reproduction signal obtained from the information storage medium irradiated with the light beam includes first information from a mark near a boundary between a region which is heated by the light beam to no less than a predetermined temperature and a first region which is at a temperature below the predetermined temperature, and second information from a mark near a boundary between the region which is heated to no less than the predetermined temperature and a second region which is at a temperature below the predetermined temperature. The signal processing circuit separates the first information from the second information, or vice versa, thereby obtaining from the reproduction signal the information recorded on the information storage medium.
    • 一种光学信息处理设备包括:光头,用于将光束辐射到信息存储介质上,并且从信息存储介质反射或衍射的光束产生再现信号,所述信息存储介质承载在其上记录的光学可读信息 ; 用于使所述光学头相对于所述信息存储介质相对移动的传送部件; 以及信号处理电路,用于接收由光头产生的再现信号并处理再现信号。 从照射光束的信息存储介质获得的再现信号包括从由光束加热到不低于预定温度的区域之间的边界附近的标记和处于低于预定温度的第一区域的第一信息 预定温度和来自加热到不低于预定温度的区域之间的边界附近的标记的第二信息和处于低于预定温度的温度的第二区域。 信号处理电路将第一信息与第二信息分开,反之亦然,从而从再现信号获得记录在信息存储介质上的信息。
