A method for effectively removing access to individual files on magnetic tape media may include: 1) encrypting a file, 2) storing the encrypted file on a tape medium, 3) storing a cryptographic key for accessing the encrypted file within a cryptographic key block located at the end of the tape medium, and then, at a subsequent point in time, 4) removing access to the encrypted file by deleting the cryptographic key for the encrypted file from the cryptographic key block located at the end of the tape medium. Corresponding systems and computer-readable media are also disclosed.
