Cylinders versus tracks...

Out of interest, which is the correct terminology when defining a single point on a disk's surface - is it better to talk in terms of cylinders, or tracks? People often seem to talk about floppy drives in terms of tracks, heads and sectors (e.g. for an 80 cylinder floppy with two sides they'll still talk in terms of tracks 1-80 in conjunction with a side number, even though the media has 160 tracks in total) Talking in terms of cylinders seems to be generally the norm with hard disks though, and perhaps seems a bit more sensible - but remember that hard disk manufacturers are the people who introduced decimal megabytes into common use :-) Personally I prefer to talk in terms of 'surface number' rather than 'head number', as a given surface could conceivably have more than one head in order to improve media latency - but I'm unsure as to whether to use cylinder/surface/sector or track/surface/sector. It's all just semantics, but for the stuff I'm currently working on I'd rather go with the 'correct' version even if that happens not to be the one most commonly used... cheers Jules
