1Tips for MMC RAW mode writing. 2 3 This allows to do disk at once recording on Philips drives that 4 do not support SAO. 5 6 You may write audio tracks in RAW mode. There are some new 7 and most likely transient options: 8 9 -raw16 Write 2352 Bytes sectors + P+Q Subchannel 10 11 -raw96r Write 2352 Bytes sectors + P+W Subchannel (R-W in raw mode) 12 13 -raw96p Write 2352 Bytes sectors + P+W Subchannel (R-W in packed mode) 14 15 NOTE that the MMC standard does not allow -dummy in RAW mode. 16 There may be drives which allow it but don't bother if it does not work. 17 18 Indices are fully supported in RAW mode. 19 20 MCN & ISRC are not yet supported in RAW mode, they are silently discarded. 21 22 If you find other problems in RAW mode or if you find 23 new bugs introduced in old write modes, please send a bug report. 24 25 Cdrecord now checks the properties of the writer. If a specific write 26 mode is not supported by the writer, cdrecord warns you and makes 27 a suggestion for a similar alternate write mode. 28 29 With the curent structure of cdrecord, it is not possible to silently 30 e.g. change the write mode from -dao to -raw96r 31 32 MMC compliant drives are automatically scanned for supported write modes. 33 This should help to make cdrecord work without manual static configuration. 34 My hope is still to have no need to know all drive properties in 35 advance, so new drives will continue to work as long as they 36 are standard compliant enough for cdrecord. 37 38EXAMPLES: 39 40 cdrecord dev=1,0 -v -raw96r *.wav 41 42 will write a audio CD in raw mode using (computed) 2448 byte sectors 43 with raw P-W subchannels. This works e.g. with Plextor drives. 44 45 46 cdrecord dev=1,0 -v -raw16 *.wav 47 48 will write a audio CD in raw mode using (computed) 2368 byte sectors 49 with raw P+Q subchannels. This works e.g. with Philips drives. 50 51 52 NOTE: The input sector size always is 2352 bytes for audio. 53 54IMPORTANT: 55 56 - if the drive supports RAW/R96R among with other raw write modes, 57 use -raw96r 58 59 - if the drive does _only_ supports RAW/R16, use -raw16 60 61 - ... else if the drive supports RAW/R96P, use -raw96p 62 63 The packed raw mode (RAW/R96P) is buggy in Plextor drives and 64 the RAW/R16 mode is buggy in TEAC drives. Plextor creates 65 unreadable disks and TEAC hangs the drive. 66 67 For this reason, it is important to select the raw writing 68 mode accoding to the notes above. 69 70
