Corona688 your sugestion works, but when I restore de information from tape with the command "dd if=/Tape_Device of=File_Name", it starts with some characters that corrupts the file, it is caused by the TAR command. How can I supress it? Also is a problem when using dd command to send de file to the tape because it most be recovered giving a filename.

If you followed Corona688's suggestions, you used "tar" then "gzip" on the files before using "dd" to write the data to tape.

What is your exact sequence of commands to retrieve the data?

The data is compressed, you need to pass it through gunzip before tar can understand it again.

Code:
dd if=/path/to/rewindingtapedevice | gunzip | tar -tf -

That will just list files. Change -tf into -xf or -xvf once you're sure it's finding the files.

Again, there is probably a better way to use tapes on AIX specifically, but that's beyond my knowledge, this is a generic UNIX fashion.
