I was recording on my MZ N707 and when it finished it would'nt eject the disc. Now when I push the open button The disk spins in the upper right corner and it tells me what disk is in there as if it were about to play. This is driving me nuts - I tried changing batteries, plugging it in and trying to take the cover off, all to no avail. Does anyone have any ideas or can point me somewhere? Thanks.
