ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a timer reservation apparatus of a disc recording and reproducing apparatus and a disc in which timer reservation information is recorded.
2. Description of the Related Art
In the Japanese laid-open patent publication No. 6-20382, an optical disc apparatus is described in which a timer reservation information on a recording reservation and a reproducing reservation for an optical disc apparatus is recorded in an optical disc. By reading out the timer reservation information recorded in the optical disc, a timer reservation of recording reservation and the reproducing reservation for optical disc apparatus is carried out.
According to such optical disc apparatus, there are advantages such that a timer reservation can be carried out with an optical disc as a unit, a plurality of the timer reservation information can be recorded, verification of the timer reservation information becomes easier, rerecording of the timer reservation information signal due to a power failure becomes unnecessary, the information signals to be recorded in the optical disc by the timer reservation can be sorted out at every disc and even if there exist a plurality of the optical disc apparatuses, the optical disc side can take an initiative in recording the information signal by the timer reservation and as a result, there is no fear that an important information signal recorded in the optical disc is erased due to overlap-recording of other information signal or the like.
By the way, in a case where a timer reservation information signal for a disc recording and reproducing apparatus is about to be recorded in a disc, relations between timer reservation information on a timer reservation information signal recorded in the disc and timer reservation information on a timer reservation information signal registered with recording and reproducing apparatus itself become a problem. To cite one example, when the respective timer reservation information on both the timer reservation information signals overlap each other in terms of time, there is a need to adjust them.
SUMMARY OF THE INVENTION
In view of such a point, an object of the present invention is to propose a timer reservation apparatus of a disc recording and reproducing apparatus which can adjust the relations between the timer reservation information on the timer reservation information signal registered with a disc recording and reproducing apparatus side and the timer reservation information on the timer reservation information signal recorded in a disc side by making the timer reservation information on the timer reservation information signal recorded in the disc side have an initiative.
Also, an other object of the present invention is to propose a disc wherein is recorded timer reservation information capable of adjusting the relations between the timer reservation information on the timer reservation information signal registered with the disc recording and reproducing apparatus side and the timer reservation information on the timer reservation information signal recorded in the disc side.
According to an aspect of the present invention, there is provided a timer reservation apparatus of a disc recording and reproducing apparatus which comprises a timer reservation information memorizing means for memorizing a timer reservation information signal; a timer reservation information recording means for recording in a predetermined area of the disc a timer reservation information signal for a disc recording and reproducing apparatus as well as a control signal indicating whether to allow or to prohibit execution of the timer reservation by the timer reservation information signal memorized in the timer reservation information memorizing means; a timer reservation information reproducing means for reproducing the timer reservation information signal as well as the control signal recorded in the predetermined area of the disc; and a timer reservation executing means for executing the timer reservation based on the timer reservation information signal read out from the timer reservation information memorizing means as well as the timer reservation information signal and the control signal reproduced by the timer reservation information reproducing means.
According to such the present invention, the timer reservation information signal for the disc recording and reproducing apparatus as well as the control signal indicating whether to allow or to prohibit the execution of the timer reservation by the timer reservation information signal memorized in the timer reservation information memorizing means are recorded in the predetermined area of the disc by the timer reservation information recording means, and the timer reservation information signal and the control signal recorded in the predetermined area of the disc are reproduced by the timer reservation information reproducing means and the timer reservation is executed by the timer reservation executing means based on the timer reservation information signal read out from the timer reservation information memorizing means memorizing the timer reservation information signal as well as the timer reservation information signal and the control signal reproduced by the timer reservation information reproducing means.
BRIEF SUMMARY OF THE INVENTION
A first aspect of the invention is a timer reservation apparatus of a disc recording and reproducing apparatus, which comprises a timer reservation information memorizing means for memorizing a timer reservation information signal; a timer reservation information recording means for recording in a predetermined area of a disc a timer reservation information signal for a disc recording and reproducing apparatus as well as a control signal indicating whether to allow or to prohibit execution of a timer reservation by a timer reservation information signal memorized in the timer reservation information memorizing means; a timer reservation information reproducing means for reproducing the timer reservation information signal as well as the control signal recorded in the predetermined area of the disc; and a timer reservation information executing means for executing the timer reservation based on the timer reservation information signal read out from the timer reservation information memorizing means as well as the timer reservation information signal and the control signal reproduced by the timer reservation information reproducing means.
A second aspect of the invention is a timer reservation apparatus of a disc recording and reproducing apparatus of the first invention, having an arrangement such that in the timer reservation apparatus of the disc recording and reproducing apparatus, in a case where the control signal is a signal which allows execution of the timer reservation by the timer reservation information signal memorized in the timer reservation information memorizing means, when timer reservation information on a timer reservation information signal memorized in the timer reservation information memorizing means and timer reservation information on a timer reservation information signal reproduced by the timer reservation information memorizing means overlap each other in terms of time, the timer reservation executing means executes the execution of the timer reservation based on the timer reservation information on the timer reservation information signal reproduced by the timer reservation information reproducing means.
A third feature of the invention is a timer reservation apparatus of a disc recording and reproducing apparatus of the first invention, having an arrangement such that in the timer reservation apparatus of the disc recording and reproducing apparatus, in a case where the timer reservation information on the timer reservation information signal reproduced by the timer reservation information reproducing means overlap each other in terms of time with respect to a recording reservation and a reproducing reservation, the timer reservation informa
