The present invention relates to a recording position correcting apparatus and method in a magnetic recording and reproducing apparatus, and more particularly, to a recording position correcting apparatus and method for correcting a tape recording position using tape intrinsic residual information.

In general, the recording and reproducing apparatus may be, for example, a video cassette recorder (VCR) or a camcorder that uses a tape as a recording medium. Such a recording and reproducing apparatus reproduces information recorded on a tape or broadcasts a broadcasting station. Signals and the like can be recorded. When recording the radio signal of a broadcasting station, it connects to a television and receives a broadcast signal as a recording input.

However, after recording is finished, the power on / off operation can be repeated before recording the next information. In this case, the tape is slowly reversed and wound upside down. Therefore, the user cannot record from the desired location, but deletes a part of the previously recorded information and executes recording from that location.

It is therefore an object of the present invention to provide a recording position correcting apparatus and method capable of designating the exact position of a tape to start recording in order to solve the above problems.

In the recording position correcting apparatus of the recording / playback apparatus provided with the key input section 10, the display section 60, and the timer 70 in order to achieve the above object,

Intrinsic residual amount detecting means for detecting a current intrinsic residual amount of tape (Remain);

Control means for controlling the tape position to be recorded by comparing the intrinsic residual value detected by the intrinsic residual amount detecting means with recording start position information;

And drive means for driving the tape position in accordance with the tape position controlled by the control means.

In the recording position correction method of the recording and reproducing apparatus for correcting the recording position of the tape in order to achieve the above object,

Comparing recording start position information with current tape intrinsic amount when the power is turned on;

Executing the reservation recording standby state by the stop mode when the recording start position information is equal to the current tape intrinsic amount by the comparing step;

And performing a rewind mode when the recording start position information is greater than the current tape intrinsic amount and executing a fast forward mode when the comparison step is smaller.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a recording position correcting apparatus according to the present invention.

In FIG. 1, the key input unit 10 is for applying a user's control command and information, and here, in particular, includes a function key for setting a recording start position.

The system control unit 20 controls all functions of the system.

The servo controller 30 keeps the rotation of the head and the movement of the tape constant under the control of the system controller 20.

The tape drive unit 40 is a means for driving the magnetic tape so that information can be recorded or reproduced on the magnetic tape and other function control through the head.

The display generator 50 is a means for performing an On Screen display function.

The display unit 60 displays a command and time information applied from the key input unit 10, and here, in particular, displays the intrinsic remaining amount of the tape.

The timer 70 functions to generate recording starting point (hereinafter referred to as RSP) information.

The natural residual amount detecting means 80 detects the natural residual value of the tape.

Next, an operation of setting the recording start position in the block diagram shown in FIG. 1 will be described.

First, if a tape is inserted into the recording / playback apparatus when the power key is turned on from the key input unit 10, the intrinsic remaining amount of the current tape is detected through the intrinsic remaining amount detecting means 80. At this time, the timer 70 sets the intrinsic remaining amount of the detected tape to the recording start position RSP to generate recording start position information.

When the recording is completed, the tape intrinsic remaining amount currently displayed on the display unit 60 is set as the recording start position.

When the recording start position setting key is input by the key input unit 10, the intrinsic amount of tape remaining at the time the key is pressed is set as the recording start position.

If the user intentionally moves the tape and moves out of the predetermined area, the tape intrinsic amount at the time when the current STOP key is input is set as the recording start position.

2 is a flowchart of a recording position correction method according to the present invention.

In FIG. 2, steps 10 to 40 are a process of comparing the recording start position information with the current tape intrinsic amount, step 50 is a process of executing the reservation recording standby state, and steps 60 to 80 are the process of recording start position information. If there is a difference between the current intrinsic tape remaining amount, the process of forwarding or reversing the tape is performed, and steps 90 to 100 are a process of resetting the current intrinsic remaining amount of the tape to the recording start position when the reservation recording is completed.

Next, the operation flow of FIG. 2 will be described with reference to FIG.

2 is an operation flowchart after recording start position information is set.

First, it is determined whether the reservation recording is currently being executed (step 10). If the reservation recording is not executed, the power is turned on before the reservation recording is executed for a predetermined time (step 30). Then, the recording start position (RSP) information is compared with the intrinsic tape remaining amount (Remain) currently displayed on the display unit 60 (steps 40 and 60).

If the recording start position (RSP) information and the tape inherent value (Remain) are the same in the step of comparing the recording start position (RSP) information and the tape inherent value (Remain), the STOP key from the key input unit 10 Set to execute the reservation recording standby state (step 50).

If the recording start position (RSP) information value is larger than the tape intrinsic value (Remain) value, the rewind (REWIND) key is set from the key input unit 10 (step 70).

If the recording start position (RSP) information value is smaller than the tape intrinsic value (Remain) value, the fast forward (FF) key is set from the key input unit 10 to reverse the tape (step 70).

In the case of the reservation execution recording in step 10, it is determined whether the reservation recording is completed (step 90). When the recording is completed, the intrinsic remaining amount of the current tape is set as the recording start position (step 100).

FIG. 3 is a diagram showing the recording start position RSP and the tape intrinsic residual amount for explaining the embodiment of steps 60 to 80 of FIG.

In Fig. 3, ① is a recording start position, and the current tape intrinsic amount is assumed to be 1 hour 20 minutes and 00 seconds, and ② is a tape position change due to a change in tape position due to a power on / off operation. It is assumed to be 30 seconds.

The area A is a portion where information such as a broadcast signal has already been recorded, and the position 1 is set as the recording start position. Where ① is the starting position to record the next broadcasting signal.

However, when the recording / playback apparatus is repeatedly turned on and off, the position of ① moves to the position of ②. When recording is performed at the position ②, the part corresponding to the area B of the area recorded in the part A is deleted.

Therefore, the current tape position is ②, but it should be moved back to ① just before starting the reservation record.

Therefore, if the user goes to the position of ① in the FF mode or the REWIND mode and executes in the reservation recording standby state by the steps 60 to 80 of FIG. 2, the user can execute the reservation recording at the desired position.

As described above, the present invention obtains the current recording start position information by using the remaining amount of tape inherent, so that the user can record information such as a broadcast signal at the exact position desired by the user.
