[johnd-mkiv]

Sure I read on here some what the rotation the groves on the disks go but I cannot find it looking at the disk do the grooves go clock wise or anti clock wise

hi there, normaly the grooves go clockwise, depending whether they are 20 groove, i think some 6 groove discs go anti clockwise.
