Title
(EN) A recorder, a disc and a method for recording information on a disc
(ZH) 记录器、盘和在盘上记录信息的方法
Abstract
(EN) When recording information in tracks or in a two-dimensional pattern care must be taken not to irradiate the adjacent tracks or pits. This results in a loss of data density on the recording medium because of the track pitch or pit distance that must be observed. A reduction in track pitch is possible to the point where the focused spot of the laser also irradiates the adjacent land area and tracks or pits. This increases the achievable data density of the recording medium. By using grooves and/or by using a dye with special absorption characteristics the effect of the irradiation of the adjacent tracks or pits can be reduced, effectively only recording marks in the desired location.
(ZH)

当在轨道中或以二维图案记录信息时,必须注意不照射邻近的轨道或凹坑。由于必须要观察到轨道间距或凹坑距离,所以这导致记录介质上数据密度的损失。有可能将轨道间距减小至这样的点:其中激光的焦斑还照射邻近脊区域以及轨道或凹坑。这提高了记录介质的可实现的数据密度。通过使用凹槽和/或通过使用具有特殊吸收特性的染料,邻近轨道的照射效应能够得到减小,从而仅在期望的位置有效地记录标记。
