Those 3" discs really were a fucking waste of time. Their capacity(storage) would've been around 20 minutes, about 125-200 Mb, so-called "CD-singles"..... HAH! A 45rpm record could easily carry an epic song like Gordon Lightfoot's 1976 release, "The Wreck Of The Edmund FitzGerald" which clocks in at over 7 minutes, and is in STEREO as well! Thus making these CD-singles REDUNDANT before they were even developed. What makes the record a "single" is that, on a turntable, one side is face-up and accessible to the pick-up arm, the other is face-down on the platter mat. The disc has the run-in groove leading to the modulated section of that groove, then out to the centre dead-wax(there's only one groove spiralling into the centre, so it's wrong to say "grooves" plural) which means there's no wasted capacity but these "CD-singles" when inserted to play, the laser, though playing one song at a time, has access directly to all the content of the disc(usually 3 or more songs, which means it's not a "CD-single") playing for 15 minutes, leaving 5 minutes wasted..... UTTERLY STUPID! The indented portion of the tray(15:25) was standard in players almost from the get-go, that's an early model player being used. The standard 5" disc with its initial 74-minute, then later 80-minute capacity is best suited to albums, even then you get a lot of wasted capacity as some albums when reissued in the format, may have only played for 30-45 minutes, leaving a lot of wasted capacity.... Ugh! As to ink discolouring the disc surface.... I've never seen that! Probably because the Australian firm, Disctronics took greater care in how they produced their discs.
