Problems solved by technology

However, when the posture of the camera changes due to the user holding it, etc., instead of being dropped, if the protection of the disk drive is given priority, the effective state of the disk drive cannot be properly maintained, and execution based on user operations is hindered. Prompt processing

Abstract

The invention provides a recording device and a driving condition control method. The recording device for recording media by a disk can not be easily influenced by the falling impact and can not reduce the processing speed based on user operations. When an HDD (30) of an internal hard disk is idle, whether the device is in a falling state or not is determined by a system control unit (21), if so, the HDD (30) is remained in the idle state, and a processing for determining whether the device is in the falling state or not by the system control unit (21) is repeated, if not, the HDD (30) is transferred from the idle state to a valid state to be capable of executing the processing based on the instructions from users.

Description

technical field [0001] The present invention relates to a recording device for recording data on disk media such as a hard disk, an optical disk, and a magneto-optical disk, and a method for controlling the driving state of a recording disk used in the recording device. Background technique [0002] In recent years, digital video cameras using a hard disk or a DVD (Digital Versatile Disc) as a recording medium have been provided. In this way, among digital video cameras using disk recording media, there are video cameras equipped with a so-called automatic power cutoff function in order to avoid useless battery consumption. [0003] The automatic power cutoff function is a function to automatically cut off the power supply of the digital camera when the digital camera is not operated for a certain period of time while the power supply is turned on. This certain period of time is usually set to several minutes. However, in a digital video camera using a disk recording mediu...
