Microdrives- has anyone managed to replace the tape ?

Postby Brane2 » Fri Feb 24, 2012 9:04 pm

Hi to all,

Since good microcartridges are getting scarce, it might be the time to try renewing the cartridge by changing the tape.

It uses exactly 1/2 of the width of ordinary audio tape, so I thought about improvising a gadget which could slice ordinary tape in half lengthwise.

But it would be nice to knoww which tape to use. Is it CrO2 or something else etc etc.

Or maybe someone has better source for 1,9 mm wide audiotape ? :roll:

Every mention of Sinclair Microdrive tape spoke of "video tape". I have, however, no idea how this might or might not be different from standard audio tape - A wild guess would assume the coating should probably be of better quality on the video tape.
What I seem to recall, VHS video tape is nearly double the thickness of a standard audio compact casette (depends a bit on the recording length).
That is, you might strive for old VHS tapes ;). Make sure you don't kill any rare Kung Fu tapes, though :lol:

Cheers,
tofro

It was a video tape base and formulation, however, there are two types of video tape: wet and dry lubricated. You cannot mix lubricant types or the video heads get dirty.

Microdrives used the wet type.

I think if you wish to cut down a donor tape, I'd recommend Panasonic HQ mastering MiniDV tapes as a compatible formulation that would work very well.

If you manage to make a suitable length and wind it appropriately and re-seal it into the cartridge *boggle* remember to join the tape with a diagonal splice.

That's all I remember.

Thanks. I'll look into that.

I had a simple scheme in mind:

- cut the original loop at head position.
- glue new tape to the end that comes from the outer end of the tape ring in the cartridge.
- pull the other end and let the glued end suck-in my new tape
- keep pulling until I pull all original tape out
- recut both ends so that they match and glue them together.

BTW, is there some special tape or kit for glueing magnetic tapes ? :)

It's standard video splice tape.

I didn't know there is such thing as "standard" splicing tape. :oops:

Whenever I did have anything with magnetic tape, I was thoroughly cautioned to keep my fingers OFF THE TAPE.

So I never saw cutting tape into pieces and then gluing them together as anything even remotely "standard".

But, a quick search found a ton of that stuff.

Live and learn, eh ? :mrgreen:

Thanks.

While we are completely off-topic :mrgreen: , here are a couple of _great_ ones, that could even be done on QL and stored even on microcartridge!
