i used to have this lil bad boy http://www.hardwarezone.com/img/data/articles/2004/1050/sony_hi-md_recorder.jpg.
it was sony's update of the minidisk format although i didnt hear much more about it after having the player. I was always blown away but the fact the disks were 1gb, and i could carry way more music than my mates with the normal minidisk. battery life was always good too, one AA battery lasted about 24 hours. Oh the days of just sticking another battery in and not having to recharge!!
