The storage capacity of any medium is fixed: conceptually, it has a
certain number of "byte storage cells" and no more. Compression
allows you to represent the original data in fewer bytes, and in a
virtual sense "get more on a tape".
An LTO2 tape has a fixed "byte storage cell" capacity of 200 GB. You
can't write 201 GB to it, but you can reduce the data by compression
such that it takes up less space. Tape drives provide transparent
compression in hardware to make that possible.
