Digital just means it comes as elements of information which can only have discrete values (for example 0 or 1, i.e. a bit) whilst analog can have any value in a continuous range of infinite precision (for example, the depth of the grooves in an LP disk or the voltage on a line like in telephone landlines).
Pretty much all computer tech nowadays is digital (though it used to be that it was mixed: for example CRT monitors actually received an analog signal), and that includes the disks (all generations since CDs store data as bits and bytes, not as continuous lines of arbitrary intensity).
Mind you, maybe the word “digital” has been redefined by the marketing types recently for use in communications with non-experts (frankly, I don’t know for sure), but for us old hands in Tech (certainly for me who am an Electronics Engineer, an area were “digital” is a technical term with precise meaning) that word being use like this to mean “download-only” just jumps out as incorrect.
That’s a redefinition of the word “digital”.
