Many differences and many similarities exist among writable DVD formats (Tables 55 and 56) Although some of the writable formats are slightly more suited for one application than for another, when it comes down to it, they all do a similar job of recording data Some have speed advantages, although faster drives and the use of CAV speeds when reading or writing CLV discs will make most of the write/record speeds moot There will be

endless arguments about which technology is better, just as there will be endless arguments about the benefits and drawbacks of cartridges The bottom line, however, is that people prefer bare discs The question of whether to use caddyless media was a point of some contention when deciding on the DVD read-only specs, but the consensus was to use bare discs like CDs Early CD-ROM drives used caddies, but they were soon

Disc and Data Details
dropped in favor of drives that could accept bare discs The customers had spoken The recommendations of the DVD Forum working groups charged with designing rewritable DVD formats also were for bare discs DVD-RAM and DVD-RW use optional cartridges (not caddies) With DVD-RAM, the engineers put more emphasis on protecting the media
Data Format
On top of the physical formats of DVD-ROM and the various writable versions sit the data and file formats They are generally similar, with minor differences for writable discs to deal with error correction and rewriting of data (Table 57)
Sector Makeup and Error Correction
Each user sector of 2048 bytes is scrambled with a bit-shifting process to help spread the data around for error correction Sixteen extra bytes are added to the beginning: 4 bytes for the sector ID (1 byte of sector information, 3 bytes for the sector number), 2 bytes for ID error detection, and 6 bytes of copyright management information (CPR_MAI) Four bytes of payload error detection code are also added to the end This makes a data sector of 2064 bytes, called a data unit 1 (Figure 58) Each data sector is arranged into 12 rows of 172 bytes, and the rows of 16 data sectors are interleaved together (spreading them apart to help with burst errors) into error correction code blocks (192 rows of 172 bytes) (Figure 59) For each of the 172 columns of the ECC block, a 16-byte outer-parity Reed-Solomon code is calculated, forming 16 new rows at the bottom For each of the 208 (192 + 16) rows of the ECC block, a 10-byte inner-parity Reed-Solomon code is calculated and appended The ECC block is then broken up into recording sectors by taking a group of 12 rows and adding 1 row of parity codes This spreads the parity codes apart for further error resilience Each recording sector is 13 rows (12 + 1) of 182 bytes (172 + 10) Each recording sector is split down the middle, and 1-byte sync codes are inserted in front of each half-row (Figure 510) This results in a recording data unit of 2418 bytes, called a data unit 3, which is identical for all DVD physical formats (DVD-ROM, DVD-R, DVD-RW, DVD-RAM, and DVD+RW) DVD-RAM media adds data between each data unit 3 before recording (Figure 511) The data unit is processed with 8/16 modulation
