Digitimes reported that the supply of optical disc drives used in notebook and desktops will remain tight in the third quarter of 2009 due to a shortage of pick-up heads (PUHs). Global suppliers of pick-up heads, including Sanyo Electric and Hitachi, have focused capacity expansion on Blu-ray Disc pick-up heads rather than DVD and CD because the former is more profitable. Second-tier notebook and desktop vendors have suffered most from the supply shortage, since suppliers have given priority to first-tier vendors such as Dell, Hewlett-Packard and Acer.
