    • A recording parameter setting device includes a trial recording parameter setting section (23) and a reproduced signal quality judging section (26). The trial recording parameter setting section (23) inquires, in accordance with the recording information, a storage section (3) containing recording parameters used for controlling heat of recording marks, and sets a trial recording parameter, wherein (a) the recording parameters are used for controlling heat of at least rear edges, (b) the recording parameters are classified in accordance with recording mark lengths, and (c) recording parameters of a predetermined recording mark length or longer are classified into a same group. The reproduced signal quality judging section (26) judges whether or not a reproduced signal obtained by reproduction of the trial recording carried out in accordance with the trial recording parameter satisfies a predetermined reproduced signal quality. If no, the recording parameters of the predetermined recording mark length or longer are further classified into detailed groups and trial recording is carried out again. If the reproduced signal satisfies the predetermined reproduced signal quality, the reproduced signal quality judging section (26) sets the trial recording parameters as a recording parameter. This makes it possible to form a recording mark capable of surely providing a good reproduced signal quality while the number of recording parameters to be used is reduced.
    • 记录参数设置装置包括试用记录参数设置部分(23)和再现信号质量判断部分(26)。 试验记录参数设定部(23)根据记录信息查询包含用于控制记录标记的热量的记录参数的存储部(3),并设定试验记录参数,其中(a)记录参数为 用于控制至少后边缘的热量,(b)记录参数根据记录标记长度分类,并且(c)预定记录标记长度或更长的记录参数被分类成同一组。 再现信号质量判断部26判断通过再现根据试用记录参数进行的试验记录而获得的再现信号是否满足规定的再现信号质量。 如果否,则将预定记录标记长度或更长的记录参数进一步分类为详细组,并再次进行试验记录。 如果再现信号满足预定的再现信号质量,则再现信号质量判断部(26)将试验记录参数设置为记录参数。 这使得可以形成能够确保提供良好再现信号质量的记录标记,同时减少要使用的记录参数的数量。

    • A recording parameter setting device setting parameters of pulse sequences forming recording marks on recording media. The device includes a storage section storing first and second look-up tables, and a recording parameter setting section for obtaining from the tables and setting parameters corresponding to recording information. The pulse sequences form at least marks equal to or longer than a first predetermined length but not longer than a maximum mark length, and include top and last sections. Also, the first lookup table stores parameters for top sections that control heat of front edges of marks classified into a same group. The second lookup table stores parameters for last sections for controlling heat of rear edges that are equal to or longer than a second predetermined recording mark length, that is longer than the first predetermined recording mark length, through the maximum recording mark length and classified into a same group.

    • A recording/reproducing device includes a laser and a laser drive carried by a pickup having a drive for movement and an input for recording information. A control controls the drives to retrieve recording parameters from a predetermined portion of the recording medium, creates pulse sequences using the input recording information and retrieved recording parameters, and forms recording marks having recording mark lengths between a predetermined and maximum lengths, a top section, a last section including a cooling period, and an intermediate period. Heat of mark front edges is controlled by recording parameters for top sections that are classified according to recording mark lengths and recording parameters of the first through the maximum recording mark lengths are classified into a same group. Heat of mark rear edges is controlled by cooling start positions for cooling periods classified according to recording mark lengths.

    • A recording parameter setting device includes a trial recording parameter setting section and a reproduced signal quality judging section. The trial recording parameter setting section sets a trial recording parameter capable of controlling a heat level at least rear edges of recording marks, classified in accordance with recording mark lengths, and grouping a predetermined recording mark length or longer into a same group. The reproduced signal quality judging section judges whether a trial recording carried out in accordance with the trial recording parameter satisfies a predetermined reproduced signal quality. If the signal quality is unsatisfactory, the trial recording parameters of the predetermined recording mark length or longer are regrouped and trial recording is carried out again until the reproduced signal satisfies the predetermined signal quality. Then, the reproduced signal quality judging section sets the trial recording parameter as the recording parameter.
