ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a data bank apparatus and method for storing and reading out information needed by a user, in a video recording and reproducing system for recording video information on a recording medium and reproducing the recorded video information.
2. Background Art
General video recording and reproducing systems, include video cassette recorders and camcorders. These video recording and reproducing systems have a basic function of recording video information on a recording medium and reproducing the recorded video information, plus additional functions which increase convenience, for instance, a parental locking function, an automatic rewinding function, a programmable recording function, etc.
With the advance of civilization, a modern person writes and manages information in note books including birthdays of family members, phone numbers of relatives and acquaintances, schedules, housekeeping duties, and check lists for the management of raising children, etc. by recording notes in a notebook. A problem exist, however, in that the notes can be easily lost, since the notes are separately provided according to the frequency in use of the books.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a data bank apparatus and the performing method thereof which can be added to a video recording and reproducing apparatus for storage and retrieval of information by a user.
To achieve the object of the present invention, a data bank apparatus is used in a video recording and reproducing system having a system controller for controlling and processing the system, a head drum including a first scanning device for recording information on a recording medium and reading out and reproducing the information, a first servo for driving the head drum and the recording medium under the control of the system controller, a video processor for processing the video signal to be recorded in the first scanning device to supply the processed video information, or for processing the video information read out by the first scanning device to generate a reproduced video signal, and a key input for transferring user-assigned instructions and information to the system controller, the data bank apparatus comprising: a second scanning device added onto the head drum for recording or reading out the information on or from a second recording medium; second servo means for driving the second scanning means added onto the head drum; a data processor for processing the digital data received from the system controller to be recorded on the second recording medium to supply it to the second scanning device, or processing the information read out by the second scanning device to supply the reproduced digital data to the system controller; a signal converting device for converting the display data processed in the system controller into a video signal form; and a mixer for mixing the display video signal generated in the video processor with the information signal generated in the signal converting device. To achieve the object of the present invention, a method performed in a data bank apparatus comprises the steps of: setting a data base mode when a data base is required and receiving user-assigned information until a record or reproduction request exists; recording the received information by finding out an information recording position when a record request exists in the information receiving step; and reproducing the information by finding out the data information on the received information when a reproduction request exists in the information receiving step.
