Specifies a disk storage device (see Example 4-16).
media_device
Specifies a sequential I/O device or access method for storage (see Example 4-15).
The media_device variable specifies a case-insensitive name for a media manager. The syntax and semantics of sequential I/O device types are platform-specific. The most common value is sbt or sbt_tape (which are synonymous values).
Note: RMAN stores the value sbt in the recovery catalog as sbt_tape for backward compatibility.
