A CPUbuilt in to a devicestarts inspection processing in response to an I/Fhaving received an inspection start command from an external terminal, switches an inspection terminal, which is a redundant terminal, over to be an input terminal with a pull-up resistor, applies a predetermined voltage to the inspection terminal, detects the input voltage of the inspection terminal, and transmits the detected input voltage as an inspection result to the external terminal

Electronic component and inspection system

A disk drive apparatus is disclosed for stabilizing a track jumping operation of an objective lens. The disk drive apparatus includes a detection section for detecting the direction that object lens is being moved by a tracking operation, and a discrimination section for discriminating the direction of the track jumping operation. A track jump movement then performed based on the detection of movement and discrimination of the track jump operation. Therefore, the track jump is stabilized without being influenced by the movement of the objective lens by the tracking operation.

Track jump apparatus capable of varying moving pulse and braking pulse

An object of this invention is to provide a recording apparatus, reproducing apparatus, recording method and reproducing method for recording or reproducing data in/from a recording medium while the recording medium is rotating by inertia after a rotation thereof by driving is stopped.

Recording apparatus, reproducing apparatus, recording method and reproducing method

An object of this invention is to provide a reproducing method and apparatus capable of facilitating a processing operation for permitting a write into a temporal memory means by reading data from a recording medium driven at a variable driving speed, permitting the write into a temporal memory means according to a signal reproduced from the recording medium and if there is a permission for the write in a period generated at a predetermined cycle and allowing the write into the temporal memory means, writing the data read to the temporal memory means.
