The well know scanning disc made by this Excel spreadsheet do not have that good result, but I found the program "DiscDesigner" by Sergei Ludanov" (KD6CJI), made for MacOS X. I've made some disks, one in NBTVA-standard withoud synch-holes (ideal for printing on A4 paper to make a simple cardboard-disc), one with synch-holes, and the third in Baird-standard 30 Lines, aspect ratio 3:7, but with synch-holes.
The advantage of those disc is, you can scale them as big as your printer can print them (there are copyshops with A3 and even A1 printers). Ideal for making a cardboard-disc just for testing or for experiments with a PCB-disc. I don't know if a PDF is good enough for a laser cut disc, but I'm afraid not.
