RECORDING MEDIUM REPRODUCING DEVICE

摘要

A recording medium reproducing device wherein power consumption is reduced by stopping disc rotation during a period when data contents are not being read, and furthermore, playability is improved and response to an external key input is improved. A system control section (106) instructs a servo control section (105) to stop rotation of a spindle motor (102) after contents data being reproduced is read by an optical pickup (103). When a residual quantity of data accumulated in a buffer memory (113) becomes a threshold value (n) or less, the spindle motor (102) is forcibly rotated and reading of contents data to be subsequently reproduced is started. The threshold value (n) is calculated by (a) a start up time of the spindle motor (102), (b) a moving time of the optical pickup (103), and (c) a reading speed of data from the buffer memory (113).
