We propose a theoretical framework for quantum data storage utilizing magnetic fields as the physical medium, with frequency-based addressing through quantum superposition states. Unlike conventional memory systems that rely on spatial addressing, our approach encodes data addresses in quantum states, making the system robust against physical displacement of the magnetic medium. We demonstrate mathematically that coherent accumulation of N sensors could yield N-squared signal amplification, addressing the weak-signal problem in magnetic field detection. Furthermore, we explore how photon-magnon entanglement enables quantum-state addressing. The recent discovery of p-wave magnetism in nickel iodide (NiI2) may provide a potential material platform for future experimental investigation, as the intrinsic spiral spin structures could form natural frequency channels. Keywords: quantum memory, magnetic storage, frequency addressing, p-wave magnetism, photon-magnon coupling
