Abstract: According to one embodiment, a recording medium drive includes a housing, a recording medium, a head actuator member stored in the housing reciprocatably about a shaft, and facing the recording medium at one end, a load tab on the end of the head actuator member, a ramp member fixed in the housing at an outer side of the recording medium, and defining a sliding surface that receives sliding of the load tab, a heater increasing a temperature of the ramp member based on a supplied driving current, a temperature sensor detecting a temperature inside the housing and outputting temperature information, a memory storing profiles of the driving current each set for a predetermined temperature range, and a control circuit supplying a predetermined value of driving current to the heater based on one of the profiles corresponding to the temperature information.

Abstract: A measuring unit measures a time (T) of a command interval by setting the end of a command generated from an upper apparatus to a start timing or by setting the start of the reception of the next command to a stop timing. A timing deciding unit varies a plurality of timings to perform a power saving on the basis of the measurement time of the command interval which was measured by the measuring unit. A power save control unit controls the apparatus to a power saving mode for a time interval from the timing decided by the timing deciding after the end of the execution of the command received from said upper apparatus until a timing when a next command is obtained.
