Popis: We describe a quantum memory spectral preparation strategy that optimizes memory efficiency and bandwidth in materials such as ^{167}Er^{3+}:Y_{2}SiO_{5} in a high-field regime, where the hyperfine structure is resolved. We demonstrate the method in ^{167}Er^{3+}:Y_{2}SiO_{5} by preparing spectrally isolated 18-dB-absorbing features on a 90% efficiency.
