This is a good point, for more reasons that mere pedantry. Describing storage methods as "digital" also encourages people two conflate two equally important but distinct concerns: 1. Durability of the physical medium over long periods of time, and 2. Our ability to decode extract information from the media even if they do physically survive. (I remember this being a hot issue several years ago, but one that seems to have faded a bit recently.)
