摘要:
When cranking is started, a control unit of an ECU determines an advance amount by which an intake valve closing timing is advanced from a fully retarded position toward a bottom dead center, and transmits the determined advance amount to a variable valve timing mechanism. After cranking is started, the control unit determines that there is an abnormality in the variable valve timing mechanism, when the advance amount is larger than 0, and when an actual intake valve closing timing, determined using an intake cam angle from a cam angle sensor and a crank angle from a crank angle sensor, is not advanced from the fully retarded position. When it is determined that there is an abnormality in the variable valve timing mechanism, the control unit outputs a control signal to an inverter to increase an output torque of a motor, which is a driving source for cranking.

Embodiments of the present invention provide a manufacturing method that can form a track guide separation area of a magnetic disk substrate constituting a patterned medium represented by a discrete track medium or bit patterned medium suitable for high recording density, uniformly on the whole surface of the magnetic disk substrate, and accurately according to the mask. According to one embodiment, a soft magnetic film, an under coating film, and a magnetic film are formed on a substrate. A mask having an arbitrary pattern shape provided for forming the track guide separation area in the magnetic film is formed on the magnetic film, and the track guide separation area is formed by irradiating ions and electrons onto the surface of the magnetic film and applying an intermittent voltage to the substrate, thereby non-magnetizing the area irradiated.
