    摘要: An information recording medium including a plurality of sectors of the present invention includes: a first spare area including a spare sector for replacing a defective sector among the plurality of sectors; a defeat management Information area for managing the replacement of the defective sector by the spare sector; and a volume space in which user data can be recorded. The volume space is configured so that a second spare area including a spare sector for replacing a defective sector among the plurality of sectors can be additionally allocated. Location information indicating a location of the second spare area is recorded in the defect management information area.

    摘要: A standard reproduction model for ensuring real time reproducing on a disk-shaped information recording medium, includes a pickup (102) that reads the real time data from the information recording medium, a buffer memory (103) that temporarily stores the real time data read by the pickup, and a decoding module (104) that reads the real time data from the buffer memory (103) and processes the read real time data. An access time Tacc of the standard reproduction model is expressed by the following formula, Tacc=A·dN+Trev+B where dN is a difference in rotational speed of the disk-shaped information recording medium, Trev is a rotation waiting time at a target access position, A and B are constants.
