Storage apparatus, control apparatus, and control method

A control apparatus of a storage apparatus configured to record a sector in a storage medium, the sector comprising a plurality of data compartments, each data compartment comprising a data region comprising data and a sync mark indicative of a position of the data region, the control apparatus comprising:

• a detector configured to control a read channel of the storage apparatus to detect the sync mark in the sector read by a reader of the storage apparatus;
• a position detector configured to control the read channel to detect the position of the data region of the read sector based on the detected sync mark;
• a data generator configured to generate data of the data region at the detected position;
• a data anomaly detector configured to detect whether the generated data is abnormal;
• and
• a data compartment recorder configured to control a storage module of the storage apparatus to record a data compartment in the storage medium identified from other data compartments, the recorded data compartment comprising a data region which comprises the generated data detected as abnormal.

A control method of a storage apparatus configured to record a sector in a storage medium, the sector comprising a plurality of data compartments, each data compartment comprising a data region comprising data and a sync mark indicative of a position of the data region, the control method comprising:

• reading the sector in the storage medium;
• detecting the sync mark in the read sector;
• determining the position of the data region of the read sector based on the detected sync mark;
• generating data of the data region at the detected position;
• detecting data anomaly whether the generated data is abnormal;
• and
• recording a data compartment in the storage medium identified from other data compartments, the recorded data compartment comprising a data region which comprises the generated data detected as abnormal.
