摘要： A CD-ROM is provided with an area for forming a character/graphic pattern. The character/graphic pattern is formed in such a way that data, which generate on the CD-ROM two sorts of pit patterns having average reflectances different from each other to a perceptible extent, are respectively recorded inside and outside the character/graphic pattern. Unless an illegal copy disc is produced by duplicating the legal original disc of the CD-ROM at a very high precision, the character/graphic pattern of the copy disc is invisibly deformed by the discrepancy between the arrangements of the pit patterns of the copy disc and the original disc.

摘要： A character and/or graphics pattern area for recording specific data is provided on a CD-ROM. When an original disk is prepared, a specific pit pattern corresponding to the specific data is recorded at a first predetermined tracking linear velocity controlled by a specific tracking linear velocity control system for each track so that a character and/or graphics pattern cannot be identified. When a copy disk is produced from the original disk, if data is recorded at a second tracking linear velocity controlled by a specific tracking linear velocity control system, the character and/or graphics pattern of visible size appears on the copy disk because of an optical reflection factor difference between areas caused by placement of the specific pit pattern corresponding to the specific data.

摘要： A realtime data recording method allows recovery of recorded file data upon occurrence of a fault, for use as a readable file. Prior to recording, initial management data are generated such that the entire area on a recording medium 1 is reflected as a recording range. After the initial management data has been recorded, data recording is started. During the recording, a writing status of the recording medium (or apparatus) is set as in-writing status, and realtime sector information generated in parallel to data recording is recorded in a non-volatile memory for management of a recording status. Upon restarting after a recording fault, the in-writing status of the recording medium 1 is read to see if the medium has been set open, and inconsistency between the recording information of the sector information and the in-writing status recording information is detected. Correct management data is recorded and re-recorded onto the recording medium.
