  Let $V$ be an operator space and $\iso(V)$ be the group of all completely
isometric bijective linear mappings on $V$. Let $G$ act on $V$ via a strongly
continuous group homomorphism $\alpha:G \to \iso (V)$. We define the full (and
reduced) operator space crossed product $V\rtimes^{\op}_{\alpha,(r)}G$ and show
that for a $C^*$-algebra with its canonical operator space structure, it
coincides with the corresponding $C^*$-algebra crossed product.
  Unfortunately, the proof of Theorem 4.3 of the paper contains a serious gap,
which leads to the withdrawal of the paper.
