摘要：

Heat-assisted magnetic recording (HAMR) is the next-generation hard disk drive technology which enables continued and significant areal density growth. There are currently three write architectures for the layout of tracks in hard disk drives: conventional magnetic recording (CMR), shingled magnetic recording (SMR), and interlaced magnetic recording (IMR). The read-back architecture multiple-sensor magnetic recording (MSMR) can be combined with the three different write architectures to increase the areal density by using two or more readers to read-back the same track. In this paper, we compare the areal density capability of HAMR CMR, HAMR SMR, and HAMR IMR combined with read-back with one reader, MSMR with two readers, and MSMR with three readers.
