Stored dynamic scattering and stored domain structure were observed in smectic C and in nematic phases of p-n-heptyloxybenzoic acid (HOBA). The sdtored texture can easily be erased with a high frequency electric field. The smallest frequency for erasure decreases with the decreasing temperature. Stored scattering centers and stored domain structure in S1 solid phase of HOBA were also observed.
