Abstract
There is provided a recording adjustment device, a recording adjustment method, and a program of which enables recording compensation for an optical disc for a high-linear density to be realized. The recording adjustment device according to an embodiment of the present technique executes filter processing on the basis of a regenerative signal obtained by reproducing data recorded in a recording medium, and a recording pattern of marks and spaces of the data, identifies an impulse response of a system, calculates a difference in amplitude between an output from the filter processing after the identification of the impulse response and the regenerative signal every edge type, and detects a slope of a step response in the vicinity of an edge position.
