Red book CD-copies

[Jarno]

Hello all,

My Sony XA-20ES plays CD-R without a problem, maybe when this player came out CD copies weren't deemed as big a problem as later on?

Regards,

Jarno.

The XA20ES is a CD player, not a SACD player, so it is no surprise that it can read CD-Rs.

The whole issue is about the drive. My stone age Denon DCD-1500 (1986) can read all my CDR's but my slightly newer DCD-1520 (1989) has problems with some CDR's and you can't see what it is, becuase all CD's are burnt with highspeed and the same brand of CD, Fuji.

Gday.

@av-trouvaille.
just a sidenote:

CD-copies do not seem to be according to this red book

the red-book is 2ch.stereo/16bit/44100Hz
only 1. of 3. layers in SACD is red-book.
In addition to other posts, opposite view:
the super audio digital disc
is just plain red-book with a audio "correction" layer,
nothing spesial about that.
Inn other words, SACD is money out the window,
both as media and sacd players
The only raw audio format that`s technicaly better
than red-book pcm data, is DVD-A.

Don't take this personally, GeirW, but you haven't a clue what you are talking about.

SACD is not "just plain red-book with a audio 'correction' layer". That's completely eff'in absurd.

The red book layer on a SACD is optional, and most SACDs do not include it. It is intended only for media compatibility with ordinary CD players, and is not used when playing SACD.

Furthermore, SACDs do not have 3 layers. They have either one or two layers: one SACD layer and one (optional) CD layer. The SACD layer contains a 2-channel version, and (optionally) a multi-channel version with six full-range channels. The great majority of SACDs include a multi-channel version. Most do not include the CD compatible layer.

The only raw audio format that`s technicaly better
than red-book pcm data, is DVD-A.

This is clearly your opinion rather than fact, and you should represent it as such. That is, "I think that..." or "in my opinion...".

mmz. read on.
i was purely pointing out that SACD
do infact exist in tree flavours.

The Three Types of the SACD Disc The SACD standard, published by Philips and Sony in March 1999, defines three possible disc types (shown above).

Type1. Type2. and Hybrid.

I surely hope that am not offending someone

Just found out, from the SCD-XB940 Service Manual, that it has got the same optical pickup as DVP-S9000ES. This seems to me that the pickup is the cause of not reading cd-r, since these both players have got this problem.

EDIT: Pickup name: KHM-220AAA

Just like I said before, it is a software "feature".

Yes, but Sony could not solve that feature on the SCD-XA333ES, and believe me, they tried.
It must be a fixed parameter, as no tuning solved the problem.
These players have problems with some mint originals, not only CDRs.
