# Erasing the Spare Media

You can erase spare media from the tape library.

You can perform one of the following erase spare media operations:

- Quick erase

  Data remains on the media, but it cannot be read or restored. The OML (On-Media-Label) is overwritten with a new OML to indicate the erased status. Use this option to logically remove data quickly and when you must keep the media onsite.

- Full erase

  All data is physically erased from the media. The process takes longer to complete than quick erase. Full erase is suitable in the following scenarios:

  - You want to move media to an offsite location.

  - You must remove all data to meet compliance regulations.

  - You want to delete sensitive data.

You can erase media from the media list of a library or at the library level.
