XEROX LASER PRINTING SYSTEMS TAPE FORMATS MANUAL 1-3
Structures with optional labels Figure 1-3 shows ANSI labeled tape structure when optional labels
are used. Optional operating system and user labels are used to
structure files, as follows, without otherwise modifying the
relationship between the required labels and files.
• Optional operating system labels of a given type follow a
required label of the same type.
• User labels of a given type directly follow a consecutive group of
operating system labels of the same type. When no optional
operating system labels are used in the label group, the user
labels directly follow a required label of the same type.
• There are no tape marks within a group of labels.
• Every label is completed on the volume where the first label of a
group was reached.
