摘要： The optical disc library apparatus of the present disclosure includes one or more magazines configured to store a plurality of optical discs, a plurality of optical disc drives configured to perform recording or reproducing on or from the optical discs, a changer mechanism configured to perform loading or ejecting any optical disc stored in the magazine to or from any optical disc drive, and a controller configured to control the changer mechanism. The magazine includes magazine-disc association information associating magazine information specifying the magazine with disc information specifying a plurality of optical discs to be stored in the magazine. The controller outputs the magazine-disc association information.

摘要： An information recording method of the present disclosure is an information recording method for recording information on a write-once information recording medium, including one or more recording layers, each of the recording layers being spiral-shaped on which a land track and a groove track are alternately repeated as recording tracks, each of the recording tracks being divided into blocks, each of the blocks being a minimum unit in which recording is performed. The information recording method includes: recording the information on the information recording medium in a unit of each of the blocks; and controlling recording on the information recording medium. In the control step, switching is performed whether to perform recording in a block to be recorded in which the information is to be recorded next among the blocks based on recording conditions of the recording tracks adjacent on both sides of the block to be recorded.

摘要： An information recording and playback device includes a recording and playback unit, and a controller. The controller divides a recording area of an optical disk into a first recording area which is at an inner circumference side, and a second recording area which is at an outer circumference side. The controller controls the recording and playback unit such that the unit records or plays back data in the first recording area at a first speed, and records or plays back data in the second recording area at a second speed slower than the first speed. The predetermined radius is set to a boundary between an area in which a control residual exceeds a predetermined reference value when servo control related to focusing and tracking is performed on the recording area of the optical disk, and an area in which the control residual does not exceed the predetermined reference value.
