In Reply to: Question for Demery: Could an SACD hold 500+ minutes of 2-channel? posted by mattpeterson on February 6, 2001 at 21:35:19:

>> Demery, you mentioned in your last post that a multichannel disc with stereo employs a lossless compression method to fit up to 74 minutes of both stereo and multi-channel program. (I got that 74 number from Sony marketing blurbs.) Correct me if I'm wrong but couldn't over 500 minutes of two-channel information be crammed onto one SACD using this same compression method? <<In principle, yes, assuming 6-channel + 2-channel equates to 4x 2-channel, you could put some 280 minutes of stereo on a single layer SACD, and since dual layer SACDs are possible you would end up with some 560 minutes of stereo on a single disc. Unfortunately, other considerations were taken into account when the SACD specification was created, and so the maximum length of a disc is limited to 256 minutes.
Hope that answers your question, Demery (Philips Electronics)
