    摘要： A high-density optical recording medium and method of recording data on the optical recording medium. The optical recording medium includes a plurality of data recording/reproducing surfaces having reflectances for light passing through a pit area, a land/groove area, and a land/groove area on which data are recorded, of a data recording/reproducing surface included between a light source for emitting light and a recording/reproducing surface selected from the plurality of data recording/reproducing surfaces, the reflectances satisfy the expressions r1≧r2≧r3 and {(r1−r3)/r1}≦0.2, where r1, r2 and r3 are the reflectances of the pit area, the land/groove area and the land groove area on which data are recorded, respectively.

    摘要： A writing strategy parameters indexing method and a recording apparatus therefor. The writing strategy parameters indexing method includes operations of receiving an NRZ sequence; moving the NRZ sequence by as much as a bit with respect to a channel block using a slide-window having a length of N bits; determining whether a bit pattern of the NRZ sequence in the window-slide has a predetermined bit pattern; extracting writing strategy parameters corresponding to the predetermined bit pattern when the bit pattern of the NRZ sequence in the window-slide has the predetermined pattern; and generating recording pulses using the writing strategy parameters.
