Abrégé
(EN)
The invention relates to a method and a recording device for formatting and recording on a multi-layer phase-change type optical disc (10). The method includes, for example, recording areas on a first (12) and a second layer (18) of the optical disc (10) according to a predefined sequence, thus ensuring that an area of the first layer (12) where through an incident radiation beam (16) passes is always fully written or fully empty when recording on the second layer (18) in order to prevent interference with the incident radiation beam (16) from the first layer (12) when recording on the second layer (18).

(ZH)

本发明涉及一种方法和一种记录装置,用于在一种多层相变型光盘(10)上进行格式化和记录。该方法包括,例如,按照预先确定的次序在光盘(10)的第一层(12)和第二层(18)上的区域进行记录,以便保证当在第二层(18)上记录时,入射辐射束(16)通过的第一层(12)的区域总是写满的或是全部空白的,这样来防止当在第二层(18)上记录时,第一层(12)对入射辐射束(16)的干扰。
