Description

The present invention relates to an information recording apparatus capable of recording new information in a superimposed manner on a recording medium having a recorded area, and uses the information recording apparatus. It is intended to provide a device that allows a user to freely select whether or not to overwrite information based on the intention.

(B) Conventional technology When an information recording apparatus is used, for example, as a tool for an information file, a recording medium of a type capable of overwriting is used so that the recorded information can be easily edited. It is configured so that overprinting can be performed on a recording medium.

In a conventional information recording apparatus, based on a flag to be reproduced from a recording medium in which information (flag) regarding whether or not overwriting is possible, at the time of recording new information, overwriting is prohibited or partially performed. The user is allowed to select permission or all permission. For example, when the recording medium is a normal rewritable magneto-optical disc, a flag indicating whether or not the recording can be overwritten in the management information area in the disk is provided, and the flag is identified to control the overwriting. It is carried out.

(C) Problems to be Solved by the Invention However, as described above, in the case where the recording medium itself has a flag relating to overprinting, the recording method desired by the user unless the user changes the flag in the recording medium. Cannot be selected, it is not possible to easily and flexibly respond to the user's request. The process of changing this flag is generally not easy, and sometimes the change itself is difficult.

The present invention has been made in view of such a point, and an object of the present invention is to provide an information recording apparatus that allows a user to easily specify a desired recording method (whether or not to select overprinting). is there. It is another object of the present invention to provide an information recording apparatus that allows a user to easily edit the recorded contents of a recording medium based on his / her intention.

(D) Means for Solving the Problems The present invention is configured so that a recording medium on which information is recorded can be set, and new recording information is written on the already recorded information on this recording medium. In an information recording apparatus capable of overlapping recording, a first switch that allows a user to selectively designate whether or not to perform overlapping recording based on the intention, and a user designates a recording start timing based on the intention. A second switch for performing recording. When the start of recording is designated by the second switch, and when the designated state of the first switch at that time is set to the overwrite-prohibited state, the information recording means is provided on the recording medium. Is detected so that new information can be recorded on a track following the end of the recorded information.

Further, the information recording apparatus of the present invention further comprises means for determining whether there is a recordable area on the medium, and display means, wherein recording start is designated by the second switch, and at that time, When the designated state of the first switch is set to the overwrite prohibited state, if there is no recordable area on the medium, the fact is displayed to the user.

(E) Function When the user desires to record new information over the already recorded information on the recording medium, the first switch is set to a mode in which overwriting is possible. The information recording unit that has detected the recording start instruction identifies the mode of the first switch and records new information in a superimposed manner on the recording medium. When the first switch is set to the overwrite / non-overwrite mode, the information recording means identifies the mode, and after instructing the start of recording, moves the head to an empty track on the recording medium to transfer new information to the empty track. Record on an empty track. When there is no empty track, the information recording means performs processing so as not to record new information on the recording medium. Then, the fact is displayed on the display means.

(F) Embodiment An embodiment of the information recording apparatus of the present invention will be described. FIG. 1 is a block diagram illustrating a schematic configuration of the present embodiment. FIG. 2 is an operation explanatory view showing a flowchart of the operation of the present embodiment.

The information recording device 1 is configured so that a recording medium 2 on which information is recorded can be set in a detachable manner.

In this embodiment, the recording medium 2 is assumed to be a magneto-optical recording disk. However, the present invention is not limited to this, and it is possible to record information and to record new information on a recorded track. Any type may be used.

The information recording device 1 includes a first switch 3, a second switch 4, an information recording unit 5, and an output unit 6.

The first switch 3 is configured so that the user can freely select and designate whether or not to perform overwriting based on his / her intention. The designation mode of the first switch 3 is a recording mode provided in the information recording means 5. It is configured so that it can be identified by the method identification means 7. The identification result by the identification means 7 is notified to the recording control means 8.

The second switch 4 is used by the user to designate the recording start timing based on his / her intention. The presence or absence of designation by the second switch is determined by the recording control means 8 configured to monitor the state. Understood.

The information recording means 5 includes a recording method identifying means 7, a recording control means 8, a recording means 9 including a head, and a recording position detecting means 10 for detecting a position of the head with respect to the recording medium 2.

The recording means 9 performs recording of information on the recording medium using a head facing the recording medium 2, and the recording is performed based on a control signal from the recording control means 8. The head is moved toward the recording track of the recording medium 2 and changes the physical state of the recording medium 2 according to the supplied recording signal. The head is configured to be relatively movable on the track, and is also capable of detecting a change in a physical state on a recording medium and reproducing recorded information.

The recording position detecting means 10 refers to the management information in the recording medium 2, recognizes the current position of the head, and notifies the recording control means 8 of information on the track position accessed by the head. Then, the recording control means 8 causes the head of the recording means 9 to access an appropriate track based on the information on the recording position.

The output means 6 has a screen, such as a liquid crystal display, for displaying that information when the first switch is set to prohibit the overwriting and the recording medium does not have an empty track for recording new information. It is a display.

Next, the operation of the apparatus of the present invention will be described with reference to the flowchart of FIG. When the procedure starts at step S1, first, at step S2, it is determined whether or not the user wants to perform overprinting, and whether or not the state of the first switch 3 needs to be changed. As a result, when a change is required, it is determined whether or not the current state can be overwritten (step S3). As a result of the determination in step S3, if it is possible, the mode of the first switch 3 is set to "impossible".
If S4 is not possible, the mode of the first switch 3 is set to "Available" S5. When the first switch 3 is set to the mode based on the intention of the user, the intention is determined to be negative in step S2 through the processing of S2 to S5.

Next, in step S6, it is determined whether the second switch 4 has been set to ON, and if it has been set,
Inspection is made by checking the state of the first switch to determine whether or not overlap recording is possible S7.
I do. Here, if the first switch 3 is set to a state in which the overwriting is permitted, the recording method identifying means 7 detects this, and the recording control means 8 executes the recording on the recording medium 2 by the recording means 9. (Step S8).

On the other hand, if the first switch 3 is set to a state in which the overwriting is not permitted (prohibited), the recording position detecting means 10 detects the recording status up to the previous time by referring to the management information recorded in advance, and performs the recording. Determine whether there is a recordable track (recording area) on the medium 2 (step S9)
When this is present, the head is moved to a recordable position (step S10), that is, a recording start process for detecting the end of the already recorded information on the recording medium and recording new information on a track following the end. (Step S8) is performed. Based on the above determination (step S9), when it is determined that there is no recordable position, processing for displaying that fact on the output means 6 is executed (step S11).

(G) Effect of the present invention As is apparent from the above description, the present invention provides a first switch that can be freely controlled by a user based on his / her intention, and controls the first switch. Since it is possible to freely select whether or not to perform the overprinting on the recording medium, there is an effect that the editing operation of the recording information on the recording medium becomes easy.

The information storage device further includes a second switch for designating a recording start timing based on the user's intention, so that when the recording start is designated by the second switch, the first switch at that time is designated. When the specified state is set to the overwrite prohibited state, the information recording means detects the end of the already recorded information on the recording medium and enables recording of new information on a track following the end. Therefore, overwriting can be easily prevented as necessary.

The apparatus further comprises means for determining whether there is a recordable area on the medium, and display means, wherein recording start is designated by the second switch, and the designated state of the first switch at that time is superimposed. If the recordable area does not exist on the medium when it is set to the prohibition state, the fact is displayed to the user to that effect. The exchange can be encouraged, and the operability in editing the recording medium can be further improved.
