+ * Media Entry (medent)
+ *
+ * [LABEL][+FILEMARKS][/NBYTES][@SLOT]
+ *
+ * LABEL is simple text and must be first.
+ *
+ * +FILEMARKS, /NBYTES, and @SLOT may occur in any order.
+ *
+ * FILEMARKS is a small decimal number and indicates
+ * how many filemarks to skip when using the media.
+ * 0 means begining of tape. If no +FILEMARKS is given,
+ * 1 is used if LABEL is given, 0 otherwise.
+ *
+ * NBYTES indicates the maximum amount of data on the
+ * media. This is a decimal number optionally followed
+ * by a scale character (k, m, g).
+ *
+ * SLOT is the slot address in the tape robot. It is
+ * the element address, not relative to the first
+ * slot in the robot.
