Sure you can encrypt a HDD
But do you want to if you really need the data on it and not have the encryption key there as well?
With Tape if it's stolen or lost there is very little chance that people responsible will have the ability to read the tape where as a HDD or DVD solution is a different story isn't it? Sure there is no way around a Profession Theft but these are rare and it's mostly amateurs who are responsible for lifting something that was there at the time so these are crimes of convenience not the premeditated type where Industrial Espionage is involved.
So from that prospective I see tape as far more secure than any other presently available solution.
