Data on old floppy disks (Amstrad)

Jeppe Utzon writes: "Back in 1987, when I was a teenager in high school still, I spent most evenings, nights and weekends writing small programs in BASIC on my Amstrad CPC 6128. Some of these programs were simple games, some drew grapics, some could help me with math or train me in french — and most were utterly pointless. But I never had as much satisfying fun as when writing those programs — even if noone in my family understood any of it when I proudly displayed the fruits of three sleepless nights of labour. Now, 20 years later, I still have a sealed pack of about 15 disks with all my work on them (along with a few of my favorite games) and I was wondering if it was possible to get the data out somehow so that I could run it in emulation on my Mac. I know of the emulators, but have no clue what would be needed to extract the data — or if it is even extractable after all these years. I realise the chances of the data still being intact are quite low, but I'd like to give it a shot anyways. So if anyone has any pointers it would be greatly appreciated."
