Abstract :
The hard disk drive industry is looking at synchronous design techniques (PRML) with a view to increasing storage density. Currently the high performance commercial read/write channels use (0, 4/4) codes to achieve up to 120 Mb/s data transfer rates. This paper describes a fully integrated read/write channel IC that operates at over 200 Mb/s. The single-chip solution in 0.51 /spl mu/m BiCMOS, has 20 mm/sup 2/ die and uses 0.85 W at 200 Mb/s.
