摘要： Upon scanning with an optical spot from a first address on the first recording layer as a start point for a second address on the second recording layer which is a target address for reproducing in order to detect a reproduction position, a scanning path for reaching the second address by scanning an already recorded zone of at least one of the first recording layer and the second recording layer is selected from a first scanning path to carry out seeking after a focus jump and a second scanning path to carry out seeking before the focus jump, based on a positional relationship between a known boundary position between a not-yet-recorded zone and an already-recorded zone of the first recording layer or the second recording layer and the first address.

摘要： An information recording apparatus divides a data area into a plurality of partial areas (UDA1, UDA2) (step 303), and sets defect management information including a defect management scheme for each partial area (step 305). Then, UDA1 is set to be an area where defect management is not performed and UDA2 is set to be an area where defect management is performed so that continuity of data is maintained for information recorded on the UDA1 and reliability of data is maintained for information recorded on the UDA2. Thus, it becomes possible to properly record a plurality of pieces of data whose usage and characteristics are different each other on a same information recording medium.
摘要翻译：信息记录装置将数据区域划分为多个部分区域（UDA1，UDA2）（步骤303），并且设置包括每个局部区域的缺陷管理方案的缺陷管理信息（步骤305）。然后，将UDA1设定为不执行缺陷管理的区域，将UDA2设定为进行缺陷管理的区域，以便对记录在UDA1上的信息保持数据的连续性，并且对于记录的信息保持数据的可靠性在UDA2上。因此，可以在相同的信息记录介质上适当地记录其使用和特性彼此不同的多条数据。

摘要： An information storage apparatus characterized in that provided with: a data writing unit that writes the data in a data-storable information recording medium; a control information writing unit that writes control information in a predetermined region of the information recording medium, the control information being related to the data-writing by said data writing unit; and a conditional control information writing unit that, while the data writing unit is writing the data in the information recording medium, if a predetermined condition is satisfied, writes the control information in the predetermined region of the information recording medium, the control information being related to the data-writing for the meantime by the data writing unit. If the predetermined condition is satisfied, the control information is written in the predetermined region of the information recording medium. Even if the power fails unexpectedly due to a power failure, for example, the loss of written data can be limited to a minimal extent.

摘要： In recording data on an information recording medium having a plurality of recording layers, it is possible to prevent losing compatibility with a reproduction-only information recording medium when recording is complete in the middle of the data rare and an unrecorded is generated. When user data recording is complete at X in the middle of data area of layer 1, dummy data having a lead out and user data attribute are recorded on the unrecorded area generated on a layer 2. When user data recording is complete at Y in the middle of data area of layer 0, dummy data having the lead out and user data attribute are recorded in a predetermined unrecorded area on the layer 1. Thus, by filling the unrecorded area with data, it is possible to maintain compatibility with a reproduction-only information recording medium having a plurality of recording layers.
