Basically, tape has a very very high latency (on the order of minutes to hours) for random access and it has a very low number of writes (usually a few dozen) before you need to copy it to a new medium.
The drives are also quite expensive and if you use them for backups, you need to keep one ready in case the other borks it but you need the tape's data.
Lastly you need specialized tools for access since most average tools will mishandle the tape.
