Sounds plausible so the problem is probably not the head itself so as mentioned above, is the tape in proper contact with the face of the head - then try the induced hum from a demagnetiser or other field source as also mentioned above.

Remember, the output from a crystal (ceramic) pickup cartridge is many times the expected output from a tape head, so do not assume the replay amplifier is working properly.
