all tape based. That usually means miniDV tape. They DO NOT use the kind of hard drives that you see in the store. When they do use hard drives, the drives alone cost several thousand dollars and store essentially uncompressed video.
I recently bought my first cam and am getting good use out of it (Canon ZR 930, With Rode mic). As such I'm continuing to research cameras for when I step up to the next level. So I'm wondering what that next step will be? Hard drive models it turns out are only a new technology and allows for true HD so what does that mean in terms of Professional models? Do consumer Hard drive HD cams give better quality picture than professional level HDV cameras? I'm guessing pro cams have better versatility with sound equipment. How good are the cheaper HD consumer cams in comparison?
