摘要	The invention is capable of recording sub-data. An optical disk device (20) forms a recording mark (RM) along a virtual irradiation line (TL) on an optical disk (100) by controlling a laser diode (51), which is the light source, according to recorded primary data information (Da) based on primary data. Then, the optical disk device (20) forms the center of the recording mark (RM) displaced from the irradiation line (TL) in the focal direction by shifting the target depth in the focal direction according to recorded sub-data information (Db) based on sub-data.
其他摘要	本发明能够记录子数据。光盘装置（20）根据记录的主要数据信息，通过控制作为光源的激光二极管（51），沿光盘（100）上的虚拟照射线（TL）形成记录标记（RM）。（Da）基于主要数据。然后，光盘装置（20）通过根据记录的子数据信息（Db）在焦点方向上移动目标深度，形成在焦点方向上从照射线（TL）移位的记录标记（RM）的中心。基于子数据。
