Compact disc, compact disc read-only memory (CD-ROM), method for using compact disc read-only memory, and method for producing compact disc

Abstract

The invention relates to a compact disc, a compact disc read-only memory (CD-ROM), a method for using the CD-ROM and a method for producing the compact disc. The compact disc is provided with a ringlike rail, and consists of an external compact disc adjustment region which is close to an outer edge region of the compact disc, wherein the external compact disc adjustment region comprises a standard external compact disc adjustment region and an additional external compact disc adjustment region, the compact disc further includes a compact disc message which indicates the attribute of the external compact disc adjustment region. The invention further relates to a CD-ROM for reading and writing in one compact disc, comprising a compact disc adjustment unit for adjusting the compact disc with one standard external compact disc adjustment region and the additional external compact disc adjustment region once at least, and a compact disc reading unit for reading the message of the compact disc, wherein the adjustment unit can adjust according to the message read from the compact disc. The invention further relates to a method for reading the compact disc and a method for producing the compact disc.

Description

technical field [0001] The present invention relates to an optical disc with an optical disc adjustment area. The present invention also relates to an optical drive capable of scanning an optical disc with an optical disc adjustment area. The present invention also relates to a method for using an optical disc drive capable of scanning The optical disc with the calibration area, the invention also relates to a manufacturing method of the optical disc, which can manufacture the optical disc with the adjustment area of ​​the optical disc, and the invention also relates to a computer program product. Background technique [0002] In a recordable optical disc, it usually includes a first area for testing burning, which can determine the writing strategy parameter value, so that an optical drive can be used to write marks on the optical disc according to a writing strategy, and the area will be described below It is called an Optimum Power Calibration (Optimum Power Calibration, ...

AI Technical Summary

Problems solved by technology

[0007] When the optical drive performs test burning in the external disc calibration area at high disc speed, the external disc calibration area may be filled with test burning quickly, and no more test burning can be done, although the internal disc The calibration area or optimal power calibration area may not be fully used, but the drive may not be able to use the internal disc calibration area at this high speed, which as stated earlier, the angular velocity that the optical drive can provide range, only the external disc adjustment area can support such a high-speed disc speed

In fact, when burning on a recordable Blu-ray disc, the highest speed that can be applied to the entire range of the disc is quadruple speed, which can cover the inner disc adjustment area and the outer disc adjustment area, but further High-speed burning, such as six-speed, eight-time and higher speed burning, can only be performed in the external disc adjustment area

[0008] Due to the limited range of the disc calibration area, the disc calibration area may even be used up before the user data area is completely used up. In addition, because the optical drive usually performs test burning for individual burning sessions Therefore, if there are a large number of burning sections, the disc is only partially burned, and the adjustment area of ​​the disc may have been used up
