The atomic frequency comb (AFC) protocol has been particularly successful recently to demonstrate the storage of quantum information in a solid medium (rare-earth-doped crystals). The AFC is inspired by the photon-echo technique. In this paper, we show that the AFC is actually closely related to the slow-light-based storage protocols extensively used in atomic vapours. Experimental verifications are performed in thulium-doped YAG (Tm3+: YAG). We clarify the interplay between absorption and dispersion, and propose a classification of the existing protocols.
