摘要： A rotation control apparatus which can maintain an accurate rotating state even in a high density optical disk (DVD) having a structure such that parts of the sync signal are recorded at an interval different from that of the other sync signal parts. The apparatus has: a unit period signal generator for generating a period signal of a unit period; a pre-pit detector for detecting a pre-pit from the DVD; a phase difference detector for detecting a phase difference between the detection timing of the pre-pit and the unit period signal; and holding circuit for a holding the phase difference detected. The rotation of the DVD is controlled on the basis of the phase difference held at the holding circuit.

摘要： An information recording device can record a plurality of pieces of recording information, for instance, at different times, in an information recording medium provided by stacking first and second recording layers. A writing control element controls a writing element so that each piece of the information can be written over the first recording layer to the second recording layer. Furthermore, a boundary control member controls the writing element so that first boundary information is written in a recording area which is to be a boundary between the pieces of information in the first recording layer, and that second boundary information is written or ensured, in a recording area of a second recording layer which overlaps the recording area wherein the first boundary information of the first recording layer is written, as a recording area to be a boundary between the pieces of information in the second recording layer.
