mick_t Posted December 28, 2016 Report Share Posted December 28, 2016 Any math geeks out there? I'm trying to come up with a simple equation to help me find how long I can record in normal mode before having to record in MDLP2 due to disc space. So for instance, if I want to record 100 minutes of music on an 80 minute Minidisc, how long can I record before having to switch to LP2? Obviously the answer is 60 minutes but can someone help me find the equation for this? That way when I have 87 minutes to put on a 74 min MD or 18 minutes of space left and 31 minutes of music, etc... I've been hurting my brain on this for a while and can't find an easy answer, although it seems simple enough. Quote Link to comment Share on other sites More sharing options...
mick_t Posted December 28, 2016 Author Report Share Posted December 28, 2016 MD = time on Minidisc MU = time of music you wish to record X = variable (my answer) R = remainder MD - X = R. And 2R = MU - X That's as close as I can get to anything and still doesn't answer my question.... Quote Link to comment Share on other sites More sharing options...
NGY Posted December 28, 2016 Report Share Posted December 28, 2016 From MD-X=R and 2R=MU-X we can eliminate R: 2MD-2X=MU-X /+2X 2MD=MU+X /-MU 2MD-MU=X Say 100 min. music on a 74 min. md (instead of 80): 148-100=48. 74-48=26, 2x26=52, 52+48=100 There you go ;-) Quote Link to comment Share on other sites More sharing options...
mick_t Posted December 28, 2016 Author Report Share Posted December 28, 2016 That's it! Thank you! Man I wracked my brain over that... The irony is when I was last in a math class 20 years ago I was probably not paying attention and listening to a Minidisc.... Thanks so much!

Well, when I was last in a math class, there was no Minidisc to listen to, as it had not existed yet! LOL Quote Link to comment Share on other sites More sharing options...
sfbp Posted December 28, 2016 Report Share Posted December 28, 2016 I was always last in math Unfortunately there were future prize-winning mathematicians much ahead of me. So if you want X minutes on a Y disk then 2Y-X is at SP. What about the 3x3x3 cube of cheese? How many cuts do you need to make all 27 cubes? Why? (the future Nobel prizewinner got it; none of the rest of us did) Quote Link to comment Share on other sites More sharing options...
mick_t Posted December 28, 2016 Author Report Share Posted December 28, 2016 6? I've already put that equation to work! Man you have no idea how much the helps. Quote Link to comment Share on other sites More sharing options...
sfbp Posted December 28, 2016 Report Share Posted December 28, 2016 But WHY? Can't you do it in less? Quote Link to comment Share on other sites More sharing options...
NGY Posted December 28, 2016 Report Share Posted December 28, 2016 It depends on the cheese ;-) ! Quote Link to comment Share on other sites More sharing options...

sfbp Posted December 29, 2016 Report Share Posted December 29, 2016 Straight cuts with a cheesecutting wire or ordinary knife. Why 4? Quote Link to comment Share on other sites More sharing options...
PhilippeC Posted December 29, 2016 Report Share Posted December 29, 2016 Before I cannot wait to eat the cheese The cheese, is it an european or an african one ? Quote Link to comment Share on other sites More sharing options...
