Thread:Understanding what a copy is (1)

In the first sentence of the second paragraph in the section "Defining derivative works", I'm confused by the use of the term "copy":

"Under general copyright law, format shifting from one medium to another is considered a copy and therefore a derivative work."

Given what I've learned so far on this page, the use of the term copy relates to exact, verbatim copy. I'm wondering if this sentence might be more clear if we said "format shifting...is not considered an exact, verbatim copy...."

Just a heads up to a sentence that I found difficult to understand.
