Which drives read into leadin/out?

Reply #75 –
I'll just throw in a little question:
1 sample of an audio CD is 1/44,100 seconds, right? That mean, if you have an offset of let's say 100 and your drive can't overread, you'll lose ~0.002 seonds of a track (assumed that the first/last samples aren't silence anyway).

For a positive offset correction you only stand to lose something at the end of a disc.  You lose nothing at the end of a track if there's another track afterwards.

Yes, I meant the last track of the disc indeed (not a track). My bad...

But if the 1 sample == 1/44,100 s is correct, then I don't understand what's all the fuss about. Lately there are many threads about perfect DAE drives (and especially overreading capabilities). There may be some CDs out there where there isn't silence in the last/first bits of a second of the first/last tracks. Can anybody state any example discs? I personally believe that there aren't many of such CDs.
A few months ago, I also thought that the overreading capability of a drive is the most important, but I think that I've changed my mind...


Sorry funkyblue when I hijack yout thread for this statement.

Different strokes for different folks.

I have quite a few.  Discs produced in the '80s are likely to be like this, but it still occasionally happens with releases to this very day.

exec, it's fine  I just started this thread to try and find a drive that can lead into the leadin/out. The only way to learn is to ask questions, no harm in that.

Cheers

Just verfied from someone at Pioneer that the DVR-115 has these features:

It will read an accurate through stream
it will cache if you let it
it will NOT report C2 error correction
it WILL report HTOA
it will NOT over-read
and the sample offset is +48
the write offset is +18

I've been a user of EAC for a couple years and learn more and more about it every time I get motivated to rip some of my CD's from the 90's.  I have access to a Toshiba 1712, Pioneer DVR106 and 111L, and Liteon LTR52327S.  I noticed a couple discs where I was getting different CRC calculations with EAC on the last track between the LiteON, the Toshiba, and the Pioneers even though AccurateRip was generating the same checksums when the disc was ripped on all four drives.  After some investigation I found I could rip with the same EAC checksum with the Toshiba and Pioneers by turning on reading into lead-out (for the Pioneers).  That makes sense since the Pioneers have positive read correction offsets and the Toshiba is negative.  Unfortunately the LiteOn doesn't read into the lead out and has a positive read offset correction, but then again the correction is only +6.

Anyway, to answer your question, the last disc I noticed this on was "Radney Foster - Del Rio, TX 1959" released in 1992 by Arista.
