STORAGE APPARATUS AND CONTROL METHOD OF STORAGE APPARATUS

1 . A storage apparatus comprising:

a storage medium configured to include a plurality of tracks;

a head configured to write data to the storage medium;

an auxiliary storage module configured to be able to store the data; and

a controller configured to determine, during data writing, a write start position of the data, move the head to a track to which the data is to be written, start writing the data along the track when the head reaches the track, and store a piece of the data to be written between the write start position and the position where the data is started to be written into the auxiliary storage module.

2 . The storage apparatus of claim 1 , wherein the controller moves the data written into the auxiliary storage module to the storage medium.

3 . The storage apparatus of claim 1 , wherein the controller predicts the position on the storage medium where the data writing is to be started, and stores a piece of the data to be written between the write start position and the predicted position into the auxiliary storage module.

4 . A control method of a storage apparatus having a storage medium configured to include a plurality of tracks, a head configured to write data to the storage medium, and an auxiliary storage module configured to be able to store the data, the control method comprising:

determining a write start position of the data during data writing;

moving the head to a track to which the data is to be written; and

starting writing the data along the track when the head reaches the track, and storing a piece of the data to be written between the write start position and the position where the data is started to be written into the auxiliary storage module.
