Abstract: There is provided an imaging and recording system including an imaging apparatus and a recording apparatus. The imaging apparatus receives an output bit rate instruction which is issued by the recording apparatus and instructs the imaging apparatus on the first bit rate of image data to be output from the imaging apparatus.

The recording apparatus has a disk type recording medium. The recording apparatus calculates the second bit rate which allows recording on the disk type recording medium, calculates the first bit rate of image data to be output from the imaging apparatus on the basis of the second bit rate, and issues the output bit rate instruction to the imaging apparatus.

Abstract: This invention can reliably prevent removal of a disk unit by a person other than an authentic user while enabling sharing the disk unit between a plurality of users. An HDD unit (20) detachable from an information processing apparatus incorporates a memory which stores user information for user authentication, and a CPU which performs authentication processing by using the user information. If eject of the HDD unit (20) is designated, the HDD unit (20) executes authentication processing on the basis of authentication information input from the information processing apparatus in which the HDD unit (20) is mounted, and the user information stored in the memory. The HDD unit (20) notifies the information processing apparatus whether to permit/inhibit eject processing. If eject processing is permitted, the information processing apparatus ejects the HDD unit (20) by using a lock mechanism (21), motor controller (23), and the like.

Abstract: A removable hard disk drive is detachable from a computer apparatus, and includes a storage medium for storing data from the computer apparatus and a communication interface with the computer apparatus. Upon reception of eject instruction issued by the computer apparatus, the removable hard disk drive writes contents cashed in a cache memory into a disk, and shifts to an ejectable state. Upon the completion of the shift to the ejectable state, the removable hard disk drive externally outputs an eject signal. A microprocessor which controls an eject mechanism executes removable hard disk cartridge eject operation in response to the eject signal.
