    • An optical information recording and reproducing apparatus includes an irradiation unit of a signal light beam and a reference light beam required for data recording, and a cure irradiation unit having at least one of a pre-cure irradiation that irradiates a predetermined light beam on to a desired position prior to irradiating the reference light bean and the signal light beam on to the desired position when information is recorded in the desired position on an optical information recording medium and a post-cure irradiation that irradiates a predetermined light beam on to the desired position so as to make the desired position non-recordable after the information is recorded in the desired position on the recording medium. The cure irradiation unit is disposed in one driving device in a freely movable manner in the driving device.

    • On an optical disk medium, a spare area is allocated separately from a recording area. If the recording area includes a defective sector, alternate recording for the defective sector is performed in the spare area. An optical disk drive comprises: a medium information acquisition part which acquires, from the optical disk medium, medium information specific to the medium; and an area size determination part which determines the spare-area size suitable for the medium on the basis of the acquired medium information. The medium information is information about, for example, a media manufacturer, and a media type number. Further, there is provided a table which stores the relationship between the medium information and the optimum size of the spare area.
    • 在光盘介质上,与记录区分开分配备用区。 如果记录区域包括缺陷扇区,则在备用区域中执行用于缺陷扇区的备用记录。 光盘驱动器包括:介质信息获取部分,从光盘介质获取介质特有的介质信息; 以及区域尺寸确定部,其基于所获取的介质信息来确定适合于介质的备用面积尺寸。 介质信息是关于例如媒体制造商和媒体类型号的信息。 此外,提供了存储介质信息与备用区域的最佳尺寸之间的关系的表。

    • In a transient state in which the temperature difference of a drive device and a disk surface is great and the temperature of the disk surface changes successively, the issues of making a strategy suited to the temperature of the disk surface appropriate, making the irradiation angle of the laser light appropriate, and making the recording power level appropriate are regarded as problems requiring resolution. The aforementioned problems are solved by respectively detecting the temperatures of the drive device and the disk surface and, based on the same temperature difference, determining an appropriate strategy; and further by adjusting the laser light so as to irradiate at an angle appropriate to the inclination of the disk and irradiating the laser light on the disk; and determining an appropriate power level in response to the temperature of the disk surface.
    • 在驱动装置和盘面的温差大且盘面的温度相继变化的瞬态状态下,适当地制作适合于盘面温度的策略的问题使照射角度 适合的激光以及适当的记录功率水平被认为是需要解决的问题。 通过分别检测驱动装置和盘表面的温度并基于相同的温差来确定适当的策略来解决上述问题; 并且进一步通过调整激光以适合于盘的倾斜的角度照射并将激光照射在盘上; 以及响应于盘表面的温度确定适当的功率水平。
