Embodiment approach 1

[0091] Below, use Figure 1 ~ Figure 4 Embodiment 1 of the present invention will be described.

[0092] figure 1 It is a block diagram of an information processing device composed of a CD-R / RW recording / reproducing device (an example of a removable medium recording / reproducing device) and a host computer according to Embodiment 1 of the present invention. figure 2 It is a flowchart showing the flow of media recognition processing and media ejection processing of the present invention. image 3 It is a flowchart showing the flow of the media ejection unlocking process of the present invention. Figure 4 It is a flowchart showing the flow of processing for recording medium ejection prohibited information on a removable medium according to the present invention.

[0093] exist figure 1 Among them, 101 is a detachable medium (CD-ROM / R / RW optical disk in this embodiment, hereinafter referred to simply as the medium), and there are mediums in which the prohibited information i...

Embodiment approach 2

[0156] Below, use Figure 3 ~ Figure 6 Embodiment 2 will be described, and components that are the same as those in Embodiment 1 above will be given the same reference numerals, and explanations will be omitted. Media pop-up unban processing ( image 3 ) and Media Popup Prohibited Information Record Processing ( Figure 4 ) is the same as that of Embodiment 1, and thus description thereof is omitted.

Abstract

It is possible to provide a removable medium recording / reproduction device capable of preventing eject of medium without release of the eject-inhibited state even after power supply to the device is turned off. The device includes a load / eject mechanism for a removable medium for delivering the removable medium into the device where it can be reproduced or sending the removable medium out of the device; medium eject-inhibit information detection means for detecting whether a predetermined area on the medium has medium eject-inhibit information recorded; and control means operating as follows. When the medium eject-inhibit information detection means has detected recording of the medium eject-inhibit information, the control means does not change the state of switch means of the device or does not eject the medium in response to an instruction from outside the device. When no recording of the medium eject-inhibit information is detected, the control means operates the load / eject mechanism so as to eject the medium according to the state change of the switch means or an instruction from outside the device.

Description

technical field [0001] The present invention relates to a detachable media recording and reproducing device, a media ejection control method of the detachable media recording and reproducing device, and a detachable media ejection control method of an information processing device, in particular to a technology for prohibiting detachable media ejection. Background technique [0002] In the past, in information processing devices such as personal computers and game machines, removable disc-type information storage media (hereinafter referred to as optical discs as appropriate) and card-type recording media such as CD-ROM drives and semiconductor memory cards are generally used to record data. reproduction device. [0003] There are roughly two methods of exchanging these removable media. [0004] The first method is a mechanical method. The user mechanically ejects or loads the disc by pulling out / receiving the cover or the pull-out tray, or ejecting / receiving the disc itsel...
