| Notes |
| 1 Absolute MSF address repeated in the header field of data blocks. |
| 2 The CD-ROM data mode is stored in the header of data tracks. This indicates that |
| the block is part of a data pre-gap or post-gap (null), that this is a data |
| block using the auxiliary field for L-EC symbols (ECC - CD-ROM data mode one), |
| or that this is a data block using the auxiliary field for user data (CD-ROM |
| data mode two). |
| 3 Table of contents information is stored in the sub-channel of lead-in area. The |
| lead-in area is coded as track zero. Track zero and the initial 150 sector pre- |
| -gap (or audio pause) are not accessible with logical addressing. |
| 4 Value stored in table of contents with zero tolerance. |
| 5 Exact value returned by READ TOC command. |
| 6 Value stored in table of contents plus or minus 75 sectors. |
| 7 Value returned by READ TOC command plus or minus 75 blocks. |
| 8 Track relative MSF value decreases to 0 in pre-gap areas. |
| 9 Track relative logical addresses are negative in the pre-gap areas. |
| Pre-gap areas have index values of zero. |
| 10 Minimum value returned by READ CD-ROM CAPACITY - exact value depends |
| on encoding of this track and the lead out track and whether this is |
| derived from the TOC data. |
| 11 Value returned by READ TOC command - exact if lead-out track is |
| encoded as data, or plus or minus 75 blocks if encoded as audio. |
| 12 Value stored in table of contents - exact if lead-out track is coded |
| as data, or plus or minus 75 blocks if coded as audio. |
| 13 Lead-out track number is defined as 0AAh. |
