[0001] This is a Continuation of application Ser. No. 10/364,368 filed Feb. 12, 2003 which is a Continuation of application Ser. No. 09/318,830 filed May 26, 1999. The disclosures of the prior applications are hereby incorporated by reference herein in their entirety. INCORPORATION BY REFERENCE [0002] The disclosures of the following priority applications are herein incorporated by reference: [0003] Japanese Patent Application No. 10-145818 filed on May 27, 1998 [0004] Japanese Patent Application No. 10-145819 filed on May 27, 1998 BACKGROUND OF THE INVENTION [0005] 1. Field of the Invention [0006] The present invention relates to an image signal recording/reproduction apparatus, a method of image signal recording/reproduction and an image signal recording apparatus. [0007] 2. Description of the Related Art [0008] Examples of recording media employed to record images in movie cameras in the prior art include magnetic tape. In such a movie camera employing magnetic tape, when an instruction to start recording an image is issued, the drive of an imaging unit constituted of a CCD or the like starts and, after sequentially performing an operation to wind the magnetic tape onto a cylinder, an operation to set the cylinder in a steady-rotating state and an operation to advance the loaded magnetic tape to a position where recording is enabled (hereafter, these operations are collectively referred to as the preparatory operations), the camera enters a state in which recording on the magnetic tape is enabled. [0009] Since it is necessary to perform a number of operations as described above before the recording-enabled state is achieved in the movie camera described above, a certain length of time elapses after, for instance, the user operates a recording start button until the actual recording of the image signal starts. Since images cannot be captured during this time, the user may miss recording an opportunity to capture a desired scene. [0010] This problem is dealt with in movie cameras in the prior art by providing a standby state in which recording of an image signal can be started any time with the tape wound at the cylinder and the cylinder in the steady-rotating state. [0011] However, there is a problem in that, since the motor is rotating at all times in the standby state, extra power is consumed. In addition, there is a problem of the tape or the magnetic head becoming worn since the motor is rotating while the tape is stationary. [0012] Furthermore, when starting recording immediately after turning on the power at the main unit, for instance, a certain length of time must elapse before the recording can start, which may cause the user to miss recording the desired scene, as explained above. [0013] Moreover, when it becomes necessary to immediately switch to a recording operation while performing a reproduction operation in the movie camera, the recording operation cannot be started promptly for the following reason. Namely, when switching from the reproduction operation to the recording operation, the operating mode at the movie camera must be switched from the reproduction operation mode to the recording operation mode by temporarily stopping the tape. When the recording operation at the movie camera is then started, the preparatory operations described earlier are performed again before the actual recording operation starts. Thus, a significant length of time must elapse before the recording start, which may cause the user to miss recording the desired scene. SUMMARY OF THE INVENTION [0014] An object of the present invention is to provide an image signal recording/reproduction apparatus, a method of image signal recording/reproduction and an image signal recording apparatus that allow recording of a dynamic image signal, a still image signal, an audio signal or the like to start promptly. [0015] In order to achieve the object described above, the present invention comprises an imaging apparatus that captures an image of a subject to be taken, a generating apparatus that generates a dynamic image signal or a still image signal of the subject captured by the imaging apparatus, an operation apparatus that is operated to start recording of the dynamic image signal or the still image signal generated by the generating apparatus, a recording apparatus that records the dynamic image signal or the still image signal in a recording medium through mechanical drive, a reproduction apparatus that reproduces the dynamic image signal or the still image signal recorded in the recording medium through mechanical drive and a control apparatus that implements control whereby a dynamic image signal or a still image signal is recorded in a recording medium by the recording apparatus by sustaining the mechanical drive if the operation apparatus is operated while the dynamic image signal or the still image signal is being reproduced by the reproduction apparatus. [0016] According to the present invention, if the operation apparatus is operated while the dynamic image signal or the still image signal is being reproduced by the reproduction apparatus, the control apparatus interrupts the reproduction operation. [0017] According to the present invention, the recording medium may be a magneto-optical disk, and the mechanical drive mentioned above may contain the rotational drive of the magneto-optical disk. [0018] The present invention is further provided with a temporary storage device that temporarily stores a dynamic image signal or a still image signal until recording of the dynamic image signal or the still image signal in the recording medium by the recording apparatus is enabled. [0019] In addition, the present invention is provided with a control apparatus that updates the contents of the temporary storage device when the temporary storage device becomes full. [0020] Furthermore, according to the present invention, if the operation apparatus is operated while a dynamic image signal or a still image signal is being reproduced by the reproduction apparatus, the control apparatus alternately implements reproduction of the dynamic image signal or the still image signal performed by the reproduction apparatus and recording of the dynamic image signal or the still image signal performed by the recording apparatus through time sharing. [0021] Alternatively, according to the present invention, the control apparatus may simultaneously implement reproduction of the dynamic image signal or the still image signal performed by the reproduction apparatus and recording of the dynamic image signal or the still image signal performed by the recording apparatus if the operation apparatus is operated while the dynamic image signal or the still image signal is being reproduced by the reproduction apparatus.
