| 1. A data storage device comprising:
a head for accessing a recording disk in order to write data to be recorded on the disk and/or read out recorded data therefrom;
a channel configured to exchange the recorded data with said head and perform a data conversion on the recorded data; and
a controller configured to exchange the recorded data with said channel and control an exchange of the recorded data between
said channel and said head;
wherein said controller outputs a starting instruction for a data exchange with said head, and data that indicates data length
of the recorded data to be exchanged, to said channel; and
in response to the data transfer starting instruction from said controller, said channel starts exchanging with said head
the recorded data of the data length specified in the data for an amount of time corresponding to the data length output from
the controller;
wherein the exchanging of recorded data is stopped independently of the starting instruction.
