Reconstruction of a variety from $\mathscr{O}[[\hbar]]$-modules

We prove that varieties are uniquely determined by the derived category of $\mathscr{O}[[\hbar]]$-modules with coherent cohomology which is the same as $\mathscr{O}$-modules proved by A. Bondal and D. Orlov. We also generalize a theorem of Orlov.
