MiniDisc planning calculator

Calculate the best fit of SP/MONO/LP2/LP4 modes

 Try also the Hi-MD planning calculator

With the introduction of MDLP is it often hard to choose the right recording mode. This javascript calculator can calculate the "best fit" to maximize the SP or LP2 recording times - in just 3 easy steps - try it and enjoy! Hopefully to your help...see also a table with some common playlengths. On a disc SP, LP2 and LP4 modes can be mixed, but you can't join 2 different playmodes to form one long track. 

Step 1. Select the length of the disc:

80 minutes (80.59)   
74 minutes (74.59)
60 minutes (60.59)
Miyadisc (86.28) - Experimental disc - timings might not hold in the real world!
User choice Length remaining recording time in SP mode (written like this: minutes.seconds) - useful when disc have been partly recorded.

Step 2. Enter duration of the tracks/albums on the form minutes.seconds eg. 34.57 in the fields below:

+ + + + + + + + +

Step 3: Hit the button to ----------->

Select All

Note: The Mono/LP2/LP4 timings are minimums and calculated exact (+/- 1 second) - to play it safe you may add some more seconds to those modes, because the limitations within the MD recording system/recording deck may not always allow those timings calculated above - or the table below. You can also choose "User choice" and enter a shorter disc length like 80.55 instead of 80.59 as the standard for 80 min disc. For fun can you of course also enter a longer disc length...
Examples...

This table made with the calculator shows how a standard 80' disc can be used with some common playlengths:

SP + Mono/LP2

SP + LP4
