Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
82 words
A video tape recorder for use with a video tape having at least one program recorded to video recording tracks and audio recording tracks on the video tape; wherein a management database recording field is formed at a predetermined position on said video recording tracks, said management database recording field having management data recorded thereto, said management data corresponding to said program, said recorder being provided with means to utilise the management data to manage each program recorded on said video tape.
Claim 2
Dependent Claim
82 words
A video tape recorder for use with a video tape having at least one program recorded to video recording tracks and audio recording tracks on the video tape: wherein a management database recording field is formed at a predetermined position on said audio recording tracks, said management database recording field having management data recorded thereto, said management data corresponding to said program, said recorder being provided with means to utilise the management data to manage each program recorded on said video tape.
Claim 3
Dependent Claim
130 words
A video tape recorder for recording on a video tape a control signal to a control signal recording track, said control signal indicting the positions of video recording tracks on the video tape, said video recording tracks being consecutively formed diagonally relative to the running direction of said video tape, said the recorder control signal recording track being formed in the direction in which said video recording tracks are consecutively formed; wherein a management database recording field is formed at a predetermined position of said control signal recording track, said management database recording field containing management data which is recorded thereto and which is about programs recorded or preset to be recorded on said video tape, said recorder being provided with means to utilise management data to manage said programs.
Claim 4
Dependent Claim
54 words
A video tape recorder for recording at least one program onto a video tape; wherein the address data representing the recording start point of said program is recorded to the tape top part of said video tape, whereby the recorded position of said program on said video tape is managed in a concentrated manner.
Claim 5
Dependent Claim
80 words
A data recording and reproducing apparatus for management control data to management database recording fields located in recording tracks of a recording medium, said apparatus being provided with means for utilising said management data in said management database recording fields to manage the data recorded in said recording tracks or in areas with reference to said recording tracks; wherein reproducing order data representing the order in which to produce said recorded data is recorded to said management database recording fields.
Claim 6
Dependent Claim
159 words
In a recording and reproducing apparatus containing a recording head means for sequentially recording at least one program on a recording medium in the running direction thereof, said recorded program having the data on the position thereof recorded by said recording head means into a control signal recording track formed on said recording medium in the running direction thereof, said program and said position data being erased by an erase head means in recording mode from said recording medium in the running direction thereof, erasure of signals on said tape by said erase head means being followed by recording of a new program and the position data thereof onto said recording medium in the running direction thereof through the use of said recording head means in said recording mode, comprising: a control head means for reading said position data, said control head means being located upstream of said erase head mean sin the running direction of said recording medium.
Claim 7
Dependent Claim
77 words
In a data recording and reproducing apparatus having management data recorded to a management database recording field in recording tracks of a recording medium, said management data being used by said apparatus to manage the data recorded in said recording tracks, a data input device comprising: a data input means to which specification items are assigned, said data input device writing said management data to said management database recording field when said data input means is specified.
