- harddisks are constructed from an aluminum platter (conductor) coated with a magnetic metal oxide (insulator)
- floppy discs are constructed from a plastic sheet (insulator) coated with a magnetic metal oxide (insulator)
however the function of computer disks in no way depends on the property of being a conductor/insulator, only on its ability to retain tiny magnetic domains while permitting them to be easily modified.

Is a wood log a insulator or an conductor?
Wood in itself is an insulator. But when wet, the water particles can conduct electricity.. Hence wet wood will be a conductor, although not a very good conductor, since the current passes only through a very small area
If impure water is conductor of electricity then why ice is insulator?
It helps to understand WHY water with impurities is a good conductor. The reason is because, if the impurities contain ions (as is usually the case), those are relatively free to move within the water. In the case of ice, the ions would be trapped, and can't move easily.It helps to understand WHY water with impurities is a good conductor.
