    Abstract: An optical data storage device and method for operating such a device. The device has means for drawing current from an internal power source and an external power source and is also provided with switching means that switches the device between a first mode, where the internal power source is electrically connected to power driving means, and a second mode where an external power source is electrically connected to power driving means. The device has power driving means which receives power at a lower voltage rating from the internal power source than when attached to the external power source. This feature improves the electrical efficiency of the device.

    Abstract: A disc drive (100) includes a disc (126), a voice coil motor (118) with an arm (114) and a beam (140) having a first end (142) attached to the arm and a second end (160) including a window frame and a gimbal region. A bridge (182) of a gimbal strut (180) underlies the gimbal region (162). A flex circuit (262) is attached to the gimbal strut. A read/write head (204) has a preload region (166) under the bridge and a slider surface (205) on the disc. A microactuator (206) has a main body (224) and has microactuator arms (226) bonded to the read/write head and mount arms (228) bonded to the bridge. The microactuator has electrical contacts (222) connected to the flex circuit. The electrical contacts are disposed between the microactuator main body and the gimbal region.

    Abstract: A reproduction system such as a hard disk drive comprises a signal processing circuit for reproducing data by processing the signals obtained from a head. The signal processing circuit has three modes of operation, that is, stop mode where the disk drive means is at rest, normal mode where the disk drive means operates to reproduce data, and standby mode where the disk drive means operates but data is not reproduced. In the stop mode, the drive means and the signal processing circuit is shut off or supplied with zero volt; in the normal mode, the drive means and the signal processing circuit are supplied with normal power; and in the standby mode, the analog circuit in the signal processing circuit is supplied with power at voltage lower than normal.
