In supersoft X-ray sources the mass accretion rate is roughly equal to the Eddington rate, and traditional standard disks cannot be adequate. We thus propose a supercritical accretion disk (superdisk) for supersoft X-ray sources.We have found that superdisks exhibit various distinct features, compared with standard thin disks. The continuous spectra of superdisks generally become flat (vS_v ~ v^0), which are greatly different from those of disk-blackbody spectra, as expected in the usual accretion disk systems. This flat nature is not so prominent in supersoft X-ray sources, compared with that in the superdisk around a black hole, since the radial extension of the disk is much smaller. Moreover, irradiation becomes important for a smaller accretion rate system. The superdisk picture was applied to RX J0019.8+2156, and reproduced its spectra and optical light curves well.
