Hard Disk Drive SOCs

Data continues to grow, driven by video, social media, enterprise applications and the cloud. To meet this demand, hard drive manufacturers continually drive more capacity per platter in hard drives. TrueStore® read channels enable higher areal densities through superior signal-to-noise (SNR) performance and advanced signal processing features. The TrueStore® read channel also has been designed with high-volume manufacturing in mind to help lower overall hard drive manufacturing costs.
To help hard drive manufacturers to achieve cost-effective capacity, Broadcom offers TrueStore® systems-on-a-chip (SOCs) that integrate read channels, hard disk controllers, PHYs, and DDR memory interfaces on one single chip.
The hard disk controller SOC acts as the brains of hard disk drives, controlling spindle speed, head position, and read, write, and servo modes. The read channel performs the critical and immensely tricky task of converting the analog data signal from the preamp into binary bits. When writing, the read channel provides the write data pattern to the preamp while servo mode detects a range of information required by the controller to stay on track.
