The evolutionary scenario of neutron star binaries is still an essential enigma in both stellar astrophysics and high energy astrophysics. In order to explore the scenario, we include the accumulation of data on the orbits and spins of compact binaries in multi-wavelength ranging from radio to X-ray, such as radio pulsar binaries, HMXBs, and LMXBs, filling them into the so called “Corbet Diagram” which initially investigated the period of orbit ( P orb)˜ the period of spin ( P spin) correlation of HMXBs. We find that the evolutionary scenario comes more clearly and makes strong confirmation of the connection between LMXBs and radio pulsar binaries, predicted by the recycle process. However, the origins of radio pulsar binaries sre still unknown. Accretion Induced Collapse (AIP) process may be a mechanism which can explain the origin of the binary millisecond pulsars with relatively longer orbital periods. A correlation of P {orb/1/3} ˜ P {spin/-1} of LMXBs and radio pulsar binaries may exist.
