摘要： A basic data structure in a lead-in area is made coincident with each other in all of a read only type, write once type, and a rewritable type. The lead-in area is divided into a system lead-in area and a data lead-in area. A track pit and a pit pitch of pits in the system lead-in area are made longer than those in the data lead-in area. In the system lead-in area, a reproduction signal from a bit is detected in accordance with a Level Slice technique, and, in the data lead-in area and data area, a signal is detected in accordance with a PRML technique. In this manner, in any of the read only type, write once type, and rewritable type, there can be provided an information recording medium and an information reproducing apparatus or information recording and reproducing apparatus therefor, capable of a stable reproduction signal from a lead-in area of the write once type recording medium while maintaining format compatibility.

摘要： An information storage medium (1) has tracks in which information is recorded. The tracks are formed as a groove section (2) and a land section (3). The groove section (2) has a synchronous structure in which wobbles (2a) and (2b) formed on both walls of the groove section (2) are not displaced from each other in the circumferential direction of the medium, and the land section (3) has an asynchronous structure in which wobbles formed on both sides of the land section (3) are displaced from each other. A good signal is reproduced from each of the groove and land sections.

摘要： A signal can be detected based on a level slice system and detection delay time can be reduced by setting the recording density of a header field in a linear direction lower (coarse) than that of a user data recording field. Further, a signal can be detected based on the level slice system and detection delay time can be reduced by using a mark position form having a large detection margin as an information recording system of the header field. A readout error of a sector number due to a detection error is compensated for by recording address marks AM for attaining byte synchronization of the header field in both of a head portion and tail portion of information recorded in the header field.
