Data bank apparatus and method of a video recording and reproducing system

A method of operation for a video tape recorder having a data bank capability, said method comprising:

• enabling a data bank mode in response to user selection of said data bank capability;
• storing user entered data into an internal working memory of a system controller of said video tape recorder and displaying said user entered data;
• reading indexing data from a file index portion of data recording media;
• determining whether an assigned file name designated by said user constitutes a new file name in response to said indexing data;
• advancing said data recording media until a recorded file is detected which corresponds to said assigned file name, and amending said recorded file which corresponds to said assigned file name in response to said user entered data, if said assigned file name does not constitute said new file name;
• advancing said data recording media to an unrecorded portion, creating a new file corresponding to said assigned file name and amending said new file in response to said user entered data, if said assigned file name constitutes said new file name;
• enabling a reproduction function of said data bank mode in response to user selection of a reproducing key;
• reading and displaying said indexing data from said file index portion of said data recording media;
• determining whether a user designated file name exists in response to said indexing data;
• and
• advancing said data recording media until a recorded file is detected which corresponds to said user designated file name, and reading and displaying contents of said recorded file corresponding said user designated file name if said assigned file name is determined to exist.

A method of operation for a video tape recorder having a data bank capability, said method comprising:

• receiving input video signals from an external source and recording said input video signals on a video recording media via a first video head and a second video head of a rotating head drum in response to user enablement of a video recording mode;
• detecting recorded video signals recorded on said video recording media via said first video head and said second video head and providing said recorded video signals to a video processor in response to user enablement of a video reproducing mode, said video processor processing said recorded video signals for display on a display device;
• enabling a data bank mode in response to user selection of said data bank capability;
• storing user entered database data into an internal working memory of a system controller of said video tape recorder and displaying said user entered data;
• reading indexing data from a file index portion of data recording media;
• determining whether an assigned file name designated by said user constitutes a new file name in response to said indexing data;
• advancing said data recording media until a recorded file is detected which corresponds to said assigned file name, providing said user entered database data from said system controller to a data processor of said video tape recorder, modulating said database data in said data processor to generate input data signals, and recording said input data signals on said data recording media via a first data head and a second data head of said rotating head drum to amend said recorded file which corresponds to said assigned file name, if said assigned file name does not constitute said new file name;
• advancing said data recording media to an unrecorded portion of said data recording media and creating a new file corresponding to said assigned file name, providing said user entered database data from said system controller to said data processor of said video tape recorder, modulating said database data in said data processor to generate said input data signals, and recording said input data signals on said data recording media via said first data head and said second data head of said rotating head drum to amend said new file, if said assigned file name constitutes said new file name;
• enabling reproduction function of said data bank mode in response to user selection of a reproducing key;
• reading and displaying said indexing data from said file index portion of said data recording media;
• determining whether a user designated file name exists in response to said indexing data;
• and
• advancing said data recording media until a recorded file is detected which corresponds to said user designated file name, detecting recorded data signals recorded on said data recording media via said first data head and said second data head, providing said data signals to said data processor for demodulation to generate display data, and providing said display data to an on-screen display circuit controlling a display device, if said assigned file name is determined to exist.
