We study a periodically driven one dimensional Kitaev model in the presence
of disorder. In the clean limit our model exhibits four topological phases
corresponding to the existence or non-existence of edge modes at zero and pi
quasienergy. When disorder is added, the system parameters get renormalized and
the system may exhibit a topological phase transition. When starting from the
Majorana π Mode (MPM) phase, which hosts only edge Majoranas with
quasienergy pi, disorder induces a transition into a neighboring phase with
both pi and zero modes on the edges. We characterize the disordered system
using (i) exact diagonalization (ii) Arnoldi mapping onto an effective tight
binding chain and (iii) topological entanglement entropy
