Mode 1 or Mode 2/XA?

plexdude · 19-12-2002

I'd like to know, does it really matter what mode is used for burning a CD? Should one of them be always used for a certain type of CD? For example, should Mode 1 be used for Data discs while Mode 2 be used for Audio discs or vice versa?

Mode 1 for data, mp3, etc becuase it incorporates good error correction coding.
Mode 2 only for vcd/svcd movie cd's.

Audio is always written raw, as AUDIO

Amendment
Mode 2-1 for data
Mode 2-xa for vcd/svcd.

ISO data in XA format

Nero normally writes ISO data in the CD sector format Mode 1 . However Nero also supports the so-called XA-Format for ISO data. The XA format is an extension of ISO structures and can only be burned onto the CD in Mode 2 (another CD sector format). 'Normal' ISO Mode 1 tracks behave just like Mode2/XA tracks when read under DOS/Windows and using modern CD-ROM drives.

The latest CD-ROM drives can easily read Mode 1 and Mode2/XA-CDs. However there are still some CD-ROM drives around that cannot read the Mode 1 CDs correctly. Owners of these older drives are advised to write data in the Mode2/XA-format.
--------

MODE-1 standard 2048-byte Yellow Book sectors, with error correction

MODE-2 2336-byte sectors, usually used for CD-ROM/XA
CD-ROM/XA ( eXtended Architecture ) MODE-2 defines two forms:

FORM-1 2048 bytes of data, with error correction, for data
FORM-2 2324 bytes of data, no ecc, for audio/video

There is some confusion around about these formats...(the cdrlabs thread looks pretty good, but it can be expressed with less words

)

Audio: just plain "audio". There are no Modes...
Data:
Mode 1: "normal"
Mode 2:
- Form 1: similar to Mode 1, just different arrangement of data
- Form 2: less error correction; for vcd, svcd or any file if you use Mode2CDMaker,

You can burn any of them in RAW mode...for Mode 1 it just means more work for the burning program (which has to calculate all C3 error correction data)

I have Nero Burning ROM 7.5.7.0 and am trying to burn a DVD from an ISO in type 2 because only 1 of my three DVD's will read it in Type 1. However, My "Type 1" box in the DVD section is grayed out. I can only change it for CD's which I am obviously not trying to record. Am I missing something here?

Oh, and DVD's don't have mode 1 & mode 2.
Everything is pretty much mode 1 -> Error correction required.

----------------------------------------------------------------------------------------------
CD-ROM Mode 1: 2048 + 288 + (16) = 2352bytes
CD-ROM Mode 2: 2336 + 0 + (16) = 2352bytes
CD-ROM Mode 2 XA (CD-ROM/XA) Form 1: 2048 + 280 + (24) = 2352bytes
CD-ROM Mode 2 XA (CD-ROM/XA) Form 2: 2324 + 4 + (24) = 2352bytes

Note: The 288 error detecion/correction bytes of "CD-ROM Mode 1" contain 8 zero bytes. "CD-ROM Mode 1" has an effective third-layer error detection/correction of 280 bytes. The 4 error detection bytes of "CD-ROM XA Form 2" are optional. A 2328 user bytes, 0 error detection bytes and 24 other bytes sector is compliant as well.
----------------------------------------------------------------------------------------------

Don't be confused by the terms XA, Mode and Form used in wrong combinations and for different meanings all the time on the web. The above is as I know it in my own words and what I think to know existing for CD-ROM. It proved to be correct over a long time. The numbers are user bytes (your data) + error detection/correction bytes for those bytes + different other system bytes = 2352bytes per sector. I hope this helps a little.
