Hi, I'm a big time newbie. I got a minidisc player to record my band, and transfer some tape demo's to CD, and I just bought a pack of Sony MDR Audio Recordable Mini Disc 80 Minute. I had the connections secured, and it would record for like a minute, but the display says: MEM OVER, and that means "you tried to record, with the recorder placed where it recieved continuous vibration". But I had it stationary not touching it? I didn't see how it's getting continuous vibrations Is this a common problem? Is there something wrong with the discs? I got them on Ebay, and I only had time to try one yesterday. I also use a reg. battery, I didn't get a rechargeable one when I got the mini-disc(also purchased off Ebay). Any help would be appreciated.
