Overview
The digital optical disc media market, which started with the compact disc (CD), has developed phenomenally, and can be said to be the first result of the digital revolution of direct significance to the consumer. The audio CD is already a worldwide phenomenon, and the MD and the audio CD-R are growing rapidly. At the same time the CD-ROM, which was developed for use as external storage for personal computers, has now become an essential peripheral device in all PCs, and there is now much activity in rewritable and large capacity optical technologies, such as CD-R/RW, DVD-ROM, and DVD-RAM. In addition to the spindle motor used to rotate the disc in these devices, several other actuators are used as well. These include the focus and tracking actuators required to position the optical pickup so that it can actually read the data on the disc, the sled motor used to move the optical pickup assembly, and a tray motor to load and unload the disc. Four or five actuators are used in most optical drives, and each of these requires a driver IC. Due to the trends toward multi-functionality and more complex functions in optical disc equipment, there are now demands for driver ICs for the actuators that provide optimal specifications and performance for each type of optical drive unit. And it goes without saying that lower power consumption is also strongly desired. To respond to these market needs, Sanyo has now developed a new series of actuator driver ICs for information-handling optical disc drive units: the LA65xx Series. The LA65xx Series achieve the low saturation voltage output and high current linearity specifications that are optimal for actuator drivers for a wide range of increasingly sophisticated optical disc units by adopting Sanyo's unique product technologies with a proven track record in a wide range of actuator driver areas. At the same time, this new series provides an extensive set of on-chip additional functions to respond to the needs of the latest drive designs. Furthermore, these new products are available in packages with integral heat sinks for simplified end product thermal design.
