摘要： An optical disk drive for recording and reproducing information on an optical disk medium includes a servo circuit for controlling tracking of a light beam on a predetermined track and a servo circuit for controlling focus of the light beam on the disk surface. The disk surface is divided into a plurality of regions, and calibration values for adjusting the servo circuits are determined in each region. The calibration values are stored in a memory and are used to adjust the servo circuits during tracking on a predetermined track. The calibration values include tracking offset values, focus offset values, servo deviation threshold values and sensor gain values. A number of techniques are disclosed for automatically determining the calibration values.

摘要： Wiring between semiconductor modules and a direct current power supply circuit, which construct a three-level power conversion apparatus, is made to be low inductance, so reduction in size and cost can be attained easily. In cases where a connection is made between direct current power supplies (electrolytic capacitors) and IGBT modules of a three-level inverter, a wiring conductor for a bi-directional switch part is divided into three conductors or two conductors on a same surface, and these conductors are sandwiched by a P conductor and an N conductor, which are arranged at outer sides thereof, respectively, through insulating materials, so a three-layer wiring structure of a sealed structure is formed. As a result, wiring inductance can be made small even with a small number of laminated layers, so that the reduction in size and cost of the apparatus as a whole is achieved.
