Overview of tape files

 

Device files and tape files are different concepts. You can read this topic for what device and tape files are, as well as how both of them are used.

Device files are files that provide access to attached devices such as tapes, diskettes, printers, displays, spools, and other systems that are attached by a communications line. The device file that is described in this topic collection is a tape file, which allows access to data files on tape devices.

Each file type has its own set of unique characteristics that determines the use and capabilities the file can provide. This topic describes the characteristics and use of tape and device files for application programs.

When programs use a device file, a name represents the device file. That name identifies both the file description and, for some file types, the data itself. This manual helps you understand the following aspects of tape files so you can use their full capabilities:
