Embodiment Construction

[0020] Please refer to FIG. 1 , which is a schematic diagram of the data structure of the first embodiment of the present invention. In order to be compatible with existing optical disc formats such as CD-DA, VCD, SVCD, CD-ROM, CD-R and CD-RW, the present invention adds an E part 10 in addition to the existing MSF part 20, They are collectively referred to as EMSF time information, and the EMSF time information represents a "minute second sector" time of at least 7 digits (Digit) with at least 25 bits.

[0021] The above-mentioned MSF part 20 is an existing recording format, and it represents time information with 6-digit BCD codes (24 bits), which also includes 8-bit M part 21, 8-bit S part 22 and 8-bit Part F 23 is used to represent Minute, Second and Frame in two digits (ie two digits); in addition, Part E 10 is used to represent hundreds of digits or more in minutes Taking Figure 1 as an example, assuming that the E part 10 has 2 bits, if binary numbers are also used, the...

Abstract

The present invention is a storage method of a high-capacity optical disc recording format, which divides the time information expressing the time length or position of the data into two parts: the MSF part and the extended part E; the format and storage method of the MSF part are the same as the existing format, The extended part E is additionally used to represent the hundreds digit or more of the minute, and it is stored separately from the MSF part. When the system needs the above-mentioned time information, the MSF part and the extended part E are read separately and placed in the memory. In, make it output as complete EMSF time information. The present invention not only can use the extension part E to represent more than a hundred digit of the score, but also can reversely be compatible with all CD formats.

Description

technical field [0001] The present invention relates to a storage method of an optical disc recording format, in particular, relates to a recording format and storage method compatible with CD optical discs and applicable to high-capacity optical discs. Background technique [0002] A format using time units, which has been widely used in general music discs (CD-DA), video discs (Video CD or VCD), super video discs (Super VCD or SVCD), read-only discs (CD-ROM) , Rewritable CD (CD-R) and Rewritable CD (CD-RW) formats. The content of this time format includes three parts: minute (minute), second (second) and sector (frame or block or sector), and can usually be expressed in the form of mm:ss:ff, where 1 minute has 60 seconds, and 1 second is divided into 75 sectors. Judging from the format of mm:ss:ff, the binary coded decimal (BCD code) of 6 digits (digit: that is, numbers, or digits) is used in the format to represent the above-mentioned minutes, seconds and sectors respec...
