As has been indicated it does depend on virtual or real tape and if it is real tape has it been reused.
In RMM you can do a LISTDATASET command for the data set, I believe it still will exist if the tape hasn't been reused. If it is there then it will show the volser the data set was written to and then you could do an RMM LISTVOLUME command and see if it is still scratch. Depending on all that you may be able to put the tape back in Master status and get the data set back. Again it all depends..
