A method for reusing used area of shingled magnetic recording (SMR) drive efficiently

Disclosed is a method for reusing used area of shingled magnetic recording (SMR) drive efficiently.

SMR is one of the next generation technology for hard disk drive (HDD). SMR drive writes two or more track at a time to improve recording density. It means that SMR drive overwrites neighbor tracks when SMR drive writes data and data which has been written on these neighbor tracks is lost. So it is hard to reuse tracks on SMR drive.

The disclosure provide the method for reusing used area of shingled magnetic recording (SMR) drive efficiently by dividing the drive into two or more sectorial partitions. By dividing the drive into two or more sectorial partitions, shingled area which has obsolete data becomes wide when a user delete a file. If a track in the area has neighbor tracks that have only obsolete data, the track can be reused. This means that by dividing the drive into two or more sectorial partitions, reusable area on SMR drive increases.
