Abstract

PURPOSE:To completely eliminate the recording and reproducing waiting time for forward and reverse running and to attain continuous recording and reproduction, by using two recording and reproducting heads and performing recording and reproduction on separate tracks at forward and reverse running. CONSTITUTION:A recording track 3 at forward running and a recording track 4 at reverse running are arranged on one side (a) and another side (b) of a magnetic card 1 to its center (chained lines 2). Reproduction is carried out for the recording track 3 when the magnetic card 1 moves to the arrow 5 and for the track 3 when the card 1 moves to the arrow 6. Two heads 7 and 7a are respectively used for the tracks 3 and 4. Thus, the reproduction can be kept continuous by using the head 7 for the movement of the card to the arrow 5 and using the head 7a to the arrow 6.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recording and reproducing method and apparatus for reciprocating a magnetic card and recording and reproducing the same during forward and backward movements.

2. Description of the Related Art It has been known to use magnetic cards to record information or to reproduce recorded information, and cards in particular have characteristics that allow information to be easily searched and organized. However, in devices that perform recording and playback by moving the magnetic card back and forth, there is a problem in that recording and playback are performed only during forward movement, and therefore, continuity cannot be provided to the recording or playback operation.

For example, if the return movement of cards is fast-forwarded, the waiting time may be shortened, but it is impossible to eliminate the waiting time.

However, this invention uses two recording/playback heads and enables recording and playback along different tracks during forward and backward movements, so there is no waiting time for recording and playback during forward and backward movements, and continuous recording is possible. The above-mentioned problems of the conventional technology have been solved by making it possible to record and play back images.

To use separate tracks for forward movement and backward movement, for example, divide a magnetic card in half and use the - side for forward movement and the other side for backward movement (as shown in the attached drawing). Possible methods include arranging the track for backward movement in parallel with the track for backward movement, or providing tracks for forward movement and backward movement at corresponding positions on the front and back sides of the magnetic card, but consideration should be given to ease of movement and installation of the head etc. The embodiments are shown in the accompanying drawings. The method of this invention requires linearly reciprocating the magnetic card, providing two recording and reproducing heads, and switching the drive system of the moving device and the recording and reproducing head depending on the direction of movement of the magnetic card. This method employs a simple method of switching the input switch of the device using a magnetic card.This method uses a magnetic card/(Fig. 1) whose central part (dashed line 2) , a recording track 3 for the forward movement and a recording trunk q for the backward movement are provided in sequence, and the recording track 3 is played when the magnetic card / moves in the direction of the arrow S in the figure, and the recording track DA is used when the magnetic card l moves in the direction of the arrow S in the figure. It is set to play when moving in the direction of arrow 6,
Different heads 7.7a correspond to tracks 3 and 7, respectively. Therefore, if the magnetic card is reproduced by head 7 when it moves in the direction of arrow S, and then reproduced by head 7a when it moves in the direction of arrow 6, both reproductions will be continuous, and for example, It can also be applied to a language practice device that responds in Japanese when repeating a foreign language.Next, the device of the present invention will be explained. On the side plates g and ga with enough space to allow the magnetic card l to be inserted,
A card receiving plate t and a guide plate 10 installed opposite to the top thereof are fixed to form a machine body l/, and guide rods /ko and /3 are attached to the side plates g and ga at predetermined intervals on the upper side of the machine body /l. The head support frame I is fixed horizontally, and the head support frame I is installed so as to be slidable in the axial direction of the guide rods /2 and /3.

In the above, before the magnetic card is inserted, the protruding piece 3g of the switch 37 is in the position shown in FIG.
As shown in FIG. 3, the free end 29a of the switcher 9 is located on the right side (in the card forward direction) and protrudes upward from the four paths of the magnetic card. The magnetic card advances and the free end 2
When 9a is lowered as shown in Fig. 1tI, the switch perco 9 rotates about the mounting shaft 32 in the direction of the center IF-C3q,
The pin 3 can be removed from one end of the switch 36 (

However, the free end 30a is held down by a magnetic card (
At 1), the spring 31 is in a stretched state. However, when the magnetic card passes and the protruding end 30a rises as shown in FIG. Push the switch /(-36 in the direction of arrow 41/, move the protrusion 3g, and switch 37. When switch 37 is switched, the motor I12 force 1 is reversed and the head circuit is also switched!

However, since the free end of Switch Reno (-29, 29'a) is pressed by the magnetic card as shown in Figure 1g, the pin 3t remains at its current position, and in this state, the magnetic card is pushed from above the free end 29a. When the magnetic card / leaves the free end 29a (Fig. 1/), it rotates in the direction of arrow qs around the switch lever resting axis, and the pin 3q moves in the direction of arrow 29a. the switch 36 is moved to switch the switch 37.

In addition, by inserting a delay circuit, it is possible to provide a slight waiting time (adjustable for example, about 3 seconds to 5 seconds) when the card is reversed. According to the above embodiment, two heads were installed at a predetermined interval from the center of the magnetic card, one side for forward movement and the other side for backward movement, and they were operated alternately. I recorded and played both the forward and backward movements of
The forward movement truck and the backward movement truck are placed in parallel and close to each other,
However, two heads can be installed in parallel to accommodate this. It is also possible to use the front and back sides of a magnetic card, but in that case there is a risk that the head moving mechanism will be complicated. Further, the mechanism of the changeover switch in the embodiment is just one example, and a limit switch, a photoelectric switch, etc. may also be used by utilizing the movement of a magnetic card. Also, if the switching of the reciprocating motion and the rotation of the pinion are linked, it can be made fully automatic. However, if a fully automatic device is used in language practice where there are many opportunities to play the same passage repeatedly, it may be necessary to provide an appropriate disconnection mechanism. Although the present invention can be used in various card-type recording and reproducing devices, it is particularly suitable for language practice, memorization practice, etc. It also has the advantage that it can be used efficiently for continuous playback and that mechanisms such as fast forwarding are not required. Therefore, it is possible to make full use of the characteristics of easy searching (search of the card itself and search of recorded contents).
