The reel label should be applied with a permanent-type adhesive, so that it cannot be easily removed. It is affixed when the tape is first received by your installation. The label should contain the sequential volume serial number assigned by your installation; it may also identify your installation. The volume serial numbers are used to identify the tape reel by a unique number and to file the tapes in the tape rack. An example of a reel label is shown in Figure 1.
