摘要： An information recording and reproduction apparatus includes a data transfer controller for receiving data to be written transferred from a host computer; a cache data memory divided into a plurality of segments for temporarily storing the data to be written received by the data transfer controller; a segment connection information memory for storing segment connection information representing a logical connection state of the plurality of segments; a buffer memory controller for managing the data to be written temporarily stored in the cache data memory; and a recording and reproduction controller for writing the data to be written temporarily stored in the cache data memory into a recording medium. The buffer memory controller updates the segment connection information so as to change the logical connection state of the plurality of segments.

摘要： A recording method for an optical disc drive and an optical disc drive wherein a surrounding temperature is measured by a temperature sensor serving as temperature measuring device, a set surrounding temperature is correlated with a set recording rate by using a data table stored in an internal memory of a controller serving as correlating device, and a recording rate is changed by a digital signal processing portion serving as recording control device based on the surrounding temperature measuring result and the correlating result. The recording rate is changed by changing a ratio of a recording operation time and a recording-stop operation time with alternately repeating a recording operation and a recording-stop operation at as low a laser beam output as playback.

摘要： An information recording medium comprises a user area, and a spare area including a replacement area, wherein the replacement area may be used instead of a defective area in the user area. The user area and the spare area include a plurality of sectors. Each of the plurality of sectors includes a user data area for recording user data, and an attribute data area for recording defect replacement allowance attribute data. The defect replacement allowance attribute data indicates whether recording of the user data has been executed in a state that the execution of a defect replacement process is allowed. In the defect replacement process, the defective area in the user area is replaced with the replacement area in the spare area.
