摘要： An optical disk device capable of increasing access speed and an image pickup device having such an optical disk device. In a region at the inside of an optical disk where the rotational speed of the spindle motor reaches its limit, a CAV mode is used for access, while in a region at the outside of the optical disk where a frequency band of an RF signal processor reaches its limit, a CLV mode is used for access. High-speed access to a maximum extent in a range of performance limits of the spindle motor and the RF signal processor is achieved. A retry feature retries failed access attempts to the optical disk when access failure is determined and a controller judges whether or not a defect of the optical disk has caused the access failure. The controller further judges if the predetermined cause of the access failure repeatedly occurs in a predetermined nearby range on the optical disk.

摘要： It is provided a ceramic multilayer substrate obtained by co-sintering a low dielectric constant layer made of an insulating material of a low dielectric constant and a high dielectric constant layer of a dielectric material of a high dielectric constant. The low dielectric constant layer includes a ceramic component of xBaO-yTiO2-zZnO (“x”, “y” and “z” represent molar ratios, respectively, and satisfy the relationship: x+y+z=1; 0.09≦x≦0.20; 0.49≦y≦0.61; 0.19≦z≦0.42) and 1.0 to 5.0 weight parts of a glass component comprising boron oxide with respect to 100 weight parts of the ceramic component. The high dielectric layer is made of a barium titanate based dielectric material with CuO and Bi2O3 added thereto.

摘要： An optical disk apparatus for controlling two optical pickups in an optimized way in response to operation modes for rotating the optical disk. When receiving a request for seeking one optical pickup from a HOST, a CPU judges whether to move the other optical pickup synchronously to satisfy positional restriction of the two optical pickups. Furthermore, when operating one optical pickup upon, for example, a read request. from the HOST, the CPU judges whether to move the other pickup to follow.
