MD: length of a '74' MD
Hello, I'm just playing around with my new MD recorder and those funny MDs themselves. I just noticed that I can record 74:57 minutes on a MD marked with '74'. I wonder why the people selling those MDs just don't say it's 75 min MD? Or does the length decrease with the number of track marks? Or have I just the wrong problems?

They cant sell it as 75minute because its not - its 74 minutes 57 seconds - those 3 seconds count for a lot. - Original Message - From: Christoph Hertel [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Sunday, June 10, 2001 11:49 AM Subject: MD: length of a '74' MD Hello, I'm just playing around with my new MD recorder and those funny MDs themselves.

Actually it's 74m59s, but because each individually recorded track takes up space in two second clusters, the unused bits left over mean that only recording in one continuous session allows you to fill all of that space. Given that on average one second of space will be lost at the end of each session, that still allows for 59 sessions, probably more than most of us use (remeber session does not necessarily mean tracks, track boundaries if recorded in one session can occur mid-cluster without loss of space). Similarly 80min discs allow 80m59s recording and 60min discs if you can still find them allow 60m59. Longer play modes (mono, LP2, LP4) give a multiple of both the maximum recording time (eg. 149m58s) and the cluster size (eg. 4 secs). If you really need to get every last scrap of space out of a disc, if copying tracks from eg. several CDs, by leaving the record session in pause mode instead of stopping it whenever you change the source disc will avoid the loss of a second or so each time. Whenever the TOC is written to the MD, that will close the current cluster and lose any free space in it. PrinceGaz. From: Robert J.

Gaz wrote a bunch of correct stuff, but then, | If you really need to get every last scrap of space out of a disc, if | copying tracks from eg. several CDs, by leaving the record session in | pause mode instead of stopping it whenever you change the source disc | will avoid the loss of a second or so each time. No, that won't work; whenever you pause recording the recorder will jump to the start of the next cluster, and when you release pause it will continue from there. The only ways I can think of off-hand to get active tracks to share a cluster are these: 1. to mark a track manually while recording; 2. to let a change in subcode bits mark a new track during recording from digital input; 3. depending on the unit, to let sync mode mark a new track when sound re- sumes after silence; or 4. to divide a track after recording. In my experimentation with Sony's Smart Space, it starts the track after the silence at the beginning of a cluster when it truncates a longer silence to three seconds. | Whenever the TOC is written to the MD, that will close the current cluster | and lose any free space in it. Yes. Unavailable partial clusters (and unavailable runs shorter than six whole clusters) are recovered when the track[s] using rest of the cluster is/are deleted and the contiguous open space is at least six whole clusters. - To stop getting this list send a message containing just the word unsubscribe to [EMAIL PROTECTED]
