    • An information recording and reproducing device diffracts by a diffracting means (14) to make laser light separated into a main beam and a sub-beam, irradiates evanescent light in relation to the main beam, by an evanescent light generating means (21), to a track where a recording pit provided on a recording surface of a recording medium is formed and also irradiates evanescent light in relation to the sub-beam to be separated to a track where no recording pit provided on the recording surface of the recording medium is formed. A moving means (210) moves the evanescent light generating means to a direction to change a gap with the recording surface. Further, a judging means (40) judges an uneven state of the recording pit formed on the recording medium, a signal generating means (3161) generates a gap error signal from a signal indicative of a return light amount in relation to the sub-beam or the main beam in accordance with the result, a control means (315) controls the moving means in accordance with a gap error signal so as to make the gap become a target value in response to the uneven state to be judged.

    • An information recording apparatus (300) is for recording record information onto an information recording medium (100) comprising a first recording layer (L0 layer) and a second recording layer (L1 layer) to record therein the record information by irradiating laser light. The information recording apparatus is provided with: a recording device (352) for recording the record information into at least one of the first recording layer and the second recording layer by irradiating the laser light; and a controlling device (354) for controlling the recording device to record the record information into a target area (115a), which is a recording area of the second recording layer corresponding to a recording area (105a) of the first recording layer in which the record information is recorded, if the record information is recorded into the second recording layer.
    • 信息记录装置(300)用于将记录信息记录在包括第一记录层(L0层)和第二记录层(L1层)的信息记录介质(100)上,通过照射激光来记录记录信息。 信息记录装置具有:通过照射激光将记录信息记录到第一记录层和第二记录层中的至少一个中的记录装置(352); 以及控制装置(354),用于控制记录装置将记录信息记录到目标区域(115a)中,该目标区域是与第一记录层的记录区域(105a)对应的第二记录层的记录区域,其中 如果记录信息被记录在第二记录层中,则记录记录信息。
