For the sake of mobile applications,it is necessary to develop information storage devices which have simultaneously a large capacity and a small size.In this paper,the development of small form factor optical(SFFO)drive is summarized at f irst.Then we introduce a 5-mm-high SFFO drive which has a good readout signal with 6.8% jitter using a limit equalizer.In addition,the use of 2.3-mm-high actuator with a horizontally arranged magnetic circuit reduces the height of optical pickup,and leads to high DC and AC sensitivity for low power consumption.
For the sake of mobile applications, it is necessary to develop information storage devices which have simultaneously a large capacity and a small size. In this paper, the development of small form factor optical (SFFO) drive is summarized at f irst. a 5-mm-high SFFO drive which has a good readout signal with 6.8% jitter using a limit equalizer. In addition, the use of 2.3-mm-high actuator with a stretched magnetic circuit reduces the height of optical pickup, and leads to high DC and AC sensitivity for low power consumption.
