A servo control device includes: a phase compensator configured to generate a plurality of types of control values for controlling a driver based on a signal output from an optical pickup, and output the control values; and a transfer data generator configured to serially transfer the control values to the driver. The phase compensator sends, to the transfer data generator, a notification that the phase compensator has output a control value which needs to be sent with a reduced delay among the control values. In response to the notification, the transfer data generator determines whether or not the transfer data generator is transferring one of the control values, and if the transfer data generator is not transferring one of the control values, the transfer data generator starts transferring a control value associated with the notification among the control values.
