Issues with reading Microdrive cartridges can be down to various reasons:
a) The data is corrupt due to ageing of the magnetic tape.
b) Mechanical issue with the cartridge - often the small felt pad between the plastic case and the exposed area of tape (this sits on a small metal spring) is too worn away to apply enough pressure to push the tape against the tape head. This can be replaced with some care, but the method does not work very well.
Sometimes the pad has split and part of it has stuck to the tape itself or gone inside the cartridge - this can lead to the tape jamming or running too slowly.
c) Mechanical issue with the microdrive unit. One of the main problems here is the small rubber wheel which you can see on the left hand side of the microdrive cartridge slot when you look through it.
- The rubber wheel can rise up the metal post on which it sits (you can try pushing it back down, but you need to ensure a small gap - 0.5mm below the bottom of the wheel - I normally use a piece of thin card until the wheel is pushed back down, and then remove the card).
- The rubber wheel also becomes badly worn - luckily only the top half of the wheel wears away, therefore you can often simply turn the wheel upside down and use the other half!
d) Finally, clean the tape head, as you would a cassette tape, with some alcohol and a cotton bud.
