(Summary of the Invention) The present invention comprises a disk-shaped substrate, in which a recording medium, for example, a magnetic sheet, is stretched over one or both sides, and at least one transducer, for example, 180 This is a recording medium disk with two magnetic heads fixed at an angle of .degree.

In addition, such a recording medium disk is stored between two fixed drums coaxially arranged with a predetermined gap between them.
A flying drum is arranged to rotate at high speed coaxially with the two drums and to be detachable, and further records information signals on the recording medium disk arranged in this way and reproduces them from this.
A head device is integrally provided, and a tape-shaped recording medium, such as a magnetic tape, is guided and run on both fixed drums having such a structure, and is scanned by the two magnetic heads to record or reproduce an information signal. This is an information signal recording and reproducing device constructed as follows.

Thereby, the information signal can be read from the recording medium disk on which the data signal is recorded by another information signal recording/reproducing device, for example, a disk drive device that is one of the peripheral devices of a computer, or from the information signal recording device equipped with the information signal recording device. While reproducing the information signal from the recording medium disk on which the information signal has been recorded by the flying head device, recording the information signal while forming, for example, a diagonal magnetic track on the magnetic tape, and storing the information signal, Can be stored and preserved.

Further, the information signal is reproduced from the magnetic tape on which the information signal is pre-recorded or recorded by the information recording/reproducing device using two magnetic heads attached to the peripheral edge of the recording medium disk, and the information signal is reproduced as necessary. Then, a partial information signal of the reproduced information is recorded on or reproduced from the recording medium disk by the flying head device, and if necessary, the recording medium disk is removed from the fixed drum. It can be stored and preserved.

(Prior Art) At present, as information signal recording and reproducing devices capable of recording, reproducing, accumulating, storing, and preserving information signals, there are currently, for example, hard disk drives (hereinafter referred to as HDDs) and floppy disk drives (hereinafter referred to as FDDs). ), Streamer-3
There are rotating magnetic head devices, etc.

Currently, 3.5-inch hard disks are the mainstream HDD, but these are becoming smaller and smaller.
For example, 2.5-inch HDDs are being installed in laptop-type computers. In any case, a hard disk is made by coating an aluminum or glass substrate with a magnetic material and depositing it by sputtering or plating, and has a thickness of about 0.9 to 1.2 mm and a diameter of about 2.5 to 3 mm.
5 inch ones are becoming mainstream. Attach such a hard disk to the spindle motor and drive 3.60O
r, p, +n.

The transducer uses a so-called flying head equipped with a magnetic head, and rotates at approximately 0.
．． This is a device that writes and reads information signals by floating 15 μm.

The current mainstream FDD is one that uses a 3.5-inch floppy disk. This floppy disk is made of a sheet-like polyethylene terephthalate base with a thickness of about 40 to 125 μm, coated with a magnetic material and adhered by spunter or vapor deposition, and has a hub in the center, which is built into a shell. It is generally used so that it can be attached to and detached from a disk drive device. The rotational speed of a floppy disk is generally 300r, p, m, or 600r
r.

p, m, the data transfer rate is slow.

You can also apply the magnetic force on both sides of the floppy disk, and many have a slider.

Streamers are generally within the technical scope of tape recorders, and in the past, reel-to-reel magnetic tape was used for back-amp applications, but recently, for example,
The 8M3480 type streamer uses a cartridge containing a 1/2 inch wide magnetic tape, and uses a tape library device to store business data and information. Recent devices have become capable of automating the loading and unloading of cartridge tapes.

The mainstream rotating magnetic head device is the helical scan type, but there are 1.5 head type Ω type VTR and U-Matic type VTR for broadcasting and professional use, and β-Max type and U-Matic type VTR for consumer use. VH3 type, 8+an video type azimuth high density recording VTR, and R- for recording sound.
There are DAT, etc. These rotating magnetic head devices are mainly used for normal recording and reproducing of video information, but a rotating magnetic sheet is installed on the rotating shaft of the rotating magnetic head, and a rotating magnetic sheet is installed on the rotating shaft of the rotating magnetic head. It has also been proposed that video information is reproduced by the rotating magnetic head, recorded in a ring shape on the rotating magnetic sheet, and reproduced from this to obtain a still image.

[Problem to be solved by the invention]

Although the various information recording and reproducing devices described above have advantages, they also have the following disadvantages. Namely, 1.Many HDD models do not require replacement of the hard disk.
Therefore, the hard disk cannot be replaced.

(2) They are sensitive to garbage and need to keep the environment clean at all times.

2. In FDDs, (1) many rotate at low speeds, and a head with a slider presses both sides of the disk, resulting in poor head contact. In particular, in the case of metal media, the accuracy is poor.

(2) Disks are sensitive to temperature and humidity, making it difficult to perform high-density recording.

3. Streamers have a large capacity, but the problem is that they take a long time to access.

4. In a rotating magnetic head device, if the tape is played back in still mode for a long time, the life of the tape will be shortened, and even if the tape has not reached the end of its life, a loss (dropout) will occur in the reproduced information.

[Means to solve the problem]

In order to eliminate such drawbacks, in the present invention, a recording medium, such as a magnetic sheet, is stretched over one or both sides of a disk-shaped substrate, and at least one layer is placed on the periphery of the disk-shaped substrate.
The present invention proposes a recording medium disk having two transducers, for example, two magnetic heads fixed at an angle of 180 degrees. Further, such a recording medium disk is arranged between two fixed drums arranged coaxially with a predetermined gap between them, so as to rotate at high speed coaxially with the two drums, and to be detachable. A flying head device for recording and reproducing information signals on the recording medium disk arranged in this manner is integrally provided, and a tape-shaped recording medium, such as a magnetic tape, is guided and run on both fixed drums configured as described above. This is an information signal recording and reproducing apparatus which scans with the two magnetic heads, records information signals, and reproduces the information signals.

[Effect]

With such a configuration, data can be obtained from the recording medium disk on which data signals are recorded by another information signal recording/reproducing device, for example, a disk drive device that is one of the peripheral devices of a computer, or from the information signal recording device equipped with the data signal. While reproducing the information signal from the recording medium disk on which the information signal has been recorded by the flying head device, the information signal is recorded and stored while forming, for example, a diagonal magnetic track on the magnetic tape. , can be stored and saved.

The slip ring 117 is fixed to the rotating shaft 106 by a nut 126 on the top of its insulating layer 120.

As shown in FIG. 3, the brush 124 is held by an insulating support member 145 that has a rectangular relief hole 144 formed in the upper fixed drum 100 that communicates with the circular relief hole 102, and that fits into the relief hole 144. . In addition, the circular escape hole 102

Next, the flying heads 140a and 140b will be explained. Head suspensions 141a and 141b support the flying heads 140a and 140b at their tips, respectively, and face magnetic sheets 3a and 3b stretched over both sides of the recording medium disk 2.

52, it is wound diagonally around the upper and lower fixed drums 100, 101 over approximately half the circumference thereof and is caused to run. The lower edge of the magnetic tape on the fixed drum is formed on the outer periphery of the lower fixed drum 101 and guided by a door 153.

Next, the operation of the implementation side of the present invention will be explained with reference to FIGS. 5, 6, and 7. Incidentally, FIG. 5 is a block diagram of the configuration of the recording/reproducing system of the present invention, and FIG. 6 is an explanatory diagram of the recording track pattern when two systems of transducers are used.
FIG. 7 is an explanatory diagram of a recording 1-rack pattern when an 1-system transducer is used.

This embodiment is a recording and reproducing device having a function of integrating a disk type recording and reproducing device and a diagonal scanning rotary head type recording and reproducing device, in which the recording medium disk 1 itself performs disk recording and reproduction and/or diagonal scanning rotary head recording and reproducing device. It is something that can be done.

If information signals are recorded on the same magnetic tape using four magnetic heads 5a, 6a and 5b, 6b provided on the recording medium disk 1 as shown in the figure, two systems of recording tracks as shown in FIG. can be formed. Further, if information signals are recorded using only the two magnetic heads 5a and 6a or only the two magnetic heads 5b and 6b, one system of recording ranks 1 to 1 as shown in FIG. 7 can be formed.

The information signal can be processed in any signal format, such as a video signal, data signal, or audio signal.

First, as a first example, a recording/reproducing system for forming the two systems of recording track patterns shown in FIG. 6 will be explained using FIG. 5.

The magnetic tape 150 is provided on the inclined tape guides 151 and 152 and the lower fixed drum 101 so as to be located at the coaxial center of the upper and lower fixed drums 1OO3101 and the recording medium disk 1. It is made to travel diagonally around the drum by approximately 180 degrees. 160
is a capstan driven by a capstan motor 161, which causes the magnetic tape 150 to run at a constant speed. 162 is a disk motor that rotates the rotating shaft at a constant speed. These motors 161, 162 and the linear actuator 1 of the flying head device
43 is controlled by a control signal obtained by comparing the frequency and phase of the pulse signal from the PC coil 127 and the reference signal.

These control signals are generated by the servo circuit system 163, but since they can be constructed by a combination of existing circuit technologies, their details will be omitted.

164 generally indicates an information processing circuit system. In the illustrated case, this circuit system 164 includes a luminance signal processing circuit, a chromaticity signal processing circuit, a recording/reproducing amplifier, and the like.

In the recording and reproducing system shown in FIG. 5, input signals are sent to the information processing circuit system 164 as stereo images from the left and right sides of a subject 165 using two video cameras 166 and 167, and the input signals are sent to the information processing circuit system 164 as appropriate so that the subject 165 is magnetically recorded in a desired state on the magnetic tape 150. It is processed. The processed stereo image signal is sent to a recording amplifier,
It is supplied to the magnetic henodes 5a, 6a and 5b, 6b via the brush 124 and slip ring 117. For example, as shown in FIG. 6, an image signal obtained by a video camera 166 is recorded on the upper half recording band of the magnetic tape 150 by magnetic heads 5a and 6a while forming diagonal tracks alternately. The image signal obtained by the video camera 167 is transferred to a magnetic recording band in the lower half of the magnetic tape 150.
The tracks are recorded while forming diagonal tracks alternately by the tracks 5b and 6b. In this way, stereo images can be magnetically recorded.

In the upper part, the case where a stereo image is recorded has been described, but the information processing circuit 164 separates the television signal into a luminance signal and a color information signal and processes them as appropriate, and the magnetic head 5a,
It is also possible to record the luminance signal component by the magnetic head 6a and the color information signal component by the magnetic heads 5b and 6b, dividing them into upper and lower recording bands as shown in the recording track pattern of FIG.

Furthermore, magnetic heads 5a and 5b, magnetic heads 6a and 6
Paired with b to activate all magnetic heads,
5-6619r Multichannel Information Magnetic Recording System'', it is also possible to form two-channel recording tracks.

Next, if only the magnetic heads 5b and 6b of FIG. 2 are used,
As shown in FIG. 7, one system of recording tracks is formed, and one
System information signals can be recorded.

In this case, only half of the magnetic tape 150 is used, but in order to increase the usage efficiency, the magnetic tape 1150 can be replaced and turned upside down to use the remaining half of the recording band. It is also possible to reversely travel in the opposite direction and switch from the magnetic heads 5b, 6b to the magnetic heads 5a, 6a to record on the upper half recording band. In addition, there is a recording method as disclosed in Japanese Patent Publication No. 4027468 r Magnetic Recording and Reproducing System, that is, magnetic heads 5a and 6b or magnetic heads 6a and 5b are combined to form magnetic tracks in two upper and lower recording bands as shown in FIG. 5a-1, 6b-1, 5a-2,
6b -2-... can also be recorded alternately.

Furthermore, it goes without saying that the present invention can also be applied to a system in which only one magnetic head is used, and a magnetic tape is wound around a fixed drum over a range of approximately 360 degrees to record and reproduce data.

Next, the case where a special image such as a still image, a slow motion image, or a fast motion image is reproduced by the recording/reproducing apparatus of the present invention will be described.

Now, the magnetic chip 1150 receives the television signal using a known recording and reproducing method using the two-head 5b, 6b method, ie, for example, I
Assume that magnetic recording was performed according to the J-Irlatic method. If you want to run such a magnetic chip 1150 at a normal speed to obtain a reproduced image and reproduce the desired reproduced image as a special image, for example, although not shown, press the "special image reproduction °" button. When pressed, the television signal, for example one frame or an integral multiple thereof, is transferred to the magnetic tape 15.
0 is reproduced by the magnetic heads 5b and 6b, and transmitted to the information processing circuit 16 through the slip ring 117 and the brush 124.
4, the flying head 140b (
or 140a), and is recorded on the magnetic sheet 3b (or 3a) extending over the recording medium disk 1 in a circular or spiral magnetic track. As already mentioned, the flying head 140b (or 140a) moves the recording medium disk 1 by the linear actuator 143.
The magnetic head is driven in the diametrical direction, and the driving method is intermittently when drawing an annular magnetic track, and continuously when drawing a spiral magnetic track. However, when reproducing special images, the flying head 140
b (or 140a) to obtain a reproduction state, for example, when obtaining a still image, by scanning a part of the recorded annular magnetic track or spiral magnetic track many times, i.e. flying head 140b
(or 140a) is held in a fixed state without moving, a still image can be obtained. Similarly, if you want to obtain slow-motion or fast-motion images, use the flying nose 140b (or 14
Those images can be obtained by driving 0a) slowly or quickly. Also, if you want to get a reverse motion image,
This can be achieved by driving the flying throat 140b (or 140a) in the opposite direction to that during recording.

In either case, flying to the throat 140b (or 1
The signal reproduced in step 40a) is processed by an information processing circuit 164 and supplied to a television monitor to reproduce an image.

Next, the case where the recording/reproducing apparatus of the present invention is used as a disk drive device which is an accessory device of a computer will be explained.

The recording medium disk 1 is placed between the upper fixed drum 100 and the lower fixed drum 101 as shown in FIG.
and the annular magnetic stainless steel 16b of the recording medium disk 1 are fixed in a predetermined angular positional relationship. When installing the recording medium disk 1 in this way, remove the upper fixed drum 100 from the drum support base 103, and attach the flying head 140a.
, 140b need to be moved back and attached.

However, with the configuration shown in FIG. 4, the servo circuit system 162 drives and controls the rotating shaft 106, that is, the recording medium disk 1, and the linear actuator 143, while the flying heads 140a and 140b span the recording medium disk 1. Data signals can be recorded on the magnetic sheets 3a and 3b by forming annular magnetic tracks or spiral magnetic tracks.

Furthermore, when recording data signals on the recording medium disk 1 of the present invention, it is not necessarily necessary to use the recording/reproducing apparatus of the present invention described above, but it is necessary to record data signals by a disk drive device using the principle of an existing disk drive device. It is also possible to record and reproduce data signals.

Next, a case where the present invention is applied to a streamer will be described.

As described above, the recording medium disk 1 on which data signals have been recorded by the recording/reproducing apparatus of the present invention or by an external disk drive device is transferred to both upper and lower fixed drums 100 as shown in FIG.
．． Magnetic tape 15 installed between 101 and driven to rotate.
0 is wound diagonally around both fixed drums 100 and 101 and run.

The data signal recorded on the recording medium disk 1 is reproduced by the flying five-node 140a and/or 140b,
After being processed by the information processing circuit 164, the information is supplied to the magnetic heads 5a, 5b, 6a, and 6b fixed to the recording medium disk 1 through the brush 124 and the slip ring 117, and is recorded and stored on the magnetic tape 150.

In this case, the recording method may be any of the methods described above when recording and reproducing the television signal using the recording track patterns shown in FIGS. 6 to 8. When recording is performed by forming recording tracks, for example in the case of FIG. 6, even if a dropout occurs in one recording track system, it is rare that the data signal on the other recording track system is also lost at the same time. It is suitable for accumulating and storing data signals. Incidentally, I would like to add that when recording information signals such as data signals on the recording medium disk 1, if the same information signals are recorded on the remagnetic sheets 3a and 3b, there will be no drop or drop in the information signal during reproduction. Outs rarely occur.

In this way, data signals on the recording medium disk 1 can be recorded and accumulated on the magnetic tape 150 one after another. In this case, if a known technique is applied to record the data signal from each recording medium disk with an address signal added thereto, it will be easier to search when a desired data signal is to be retrieved.

The above has described the case where the data signal from the magnetic medium disk 1 is converted to the magnetic tape 150. However, in the recording and reproducing system shown in FIG.
It is also possible to use 67 as a mere input terminal for information signals such as data signals, and record directly on the magnetic tape 150 using a combination of magnetic heads 5a, 5b, 6a, and 6b.

Conversely, information signals such as data signals recorded on the magnetic tape 150 are reproduced by a combination of magnetic heads 5a, 5b, 6a, and 6b, and the slip ring 117, brush 124,
Flying head 140 via information processing circuit 163 etc.
a and/or 140b and recorded on the magnetic seeds 3a and/or 3b stretched over the recording medium disk 1, the recording and reproducing apparatus shown in FIG. It is also possible to remove the recording medium disk 1 from the playback device and manage and store it.

As is clear from the above explanation, the recording medium disk 1 and the magnetic tape 150 serve as a disk medium memory and a tape memory, respectively, and the recording and reproducing apparatus plays a role as a disk tape memory conversion device.

The content of the information signal handled by the recording/reproducing apparatus of the present invention can be of any format, such as a video signal, data signal, or audio signal.

In addition, in the explanation so far, the magnetic track on the magnetic chip 1150 has been explained as an oblique magnetic track, but it is also possible to form a magnetic track in the longitudinal direction of the magnetic tape and record a signal, or to record a signal in the longitudinal direction of the tape. It is also possible to record signals by forming magnetic tracks substantially perpendicular to the magnetic field.

Furthermore, although the explanation so far has been based on a magnetic recording/reproducing method, it should be added that the principle of the present invention can also be realized in a recording/reproducing method using an optical/magnetic conversion method.

〔Effect of the invention〕

As has become clear from the above explanation, the recording medium disk and its recording/reproducing apparatus of the present invention have the following effects compared to conventional ones.

A.Regarding the recording medium disk 1.A material with a small coefficient of thermal expansion is used for the base, and magnetic sheets are attached to both sides of the base with equal tension, making it possible to eliminate the effects of temperature and humidity.

2. Since the magnetic sheet can be attached to the base with high precision, it is possible to form a rotating surface with little surface runout, like a hard disk.

3. Since the flying head scans the surface of the recording medium without surface runout, it is possible to obtain optimal contact.

4. Since the magnetic sheet is stretched, even if the flying head contacts the surface of the recording medium, it is unlikely to be damaged, and the spacing loss can be reduced to, for example, about 0.02μ, making perpendicular magnetic recording possible.

5. Also, by providing a transducer on the outer periphery of the recording medium disk and converting the recording and playback between the disk and tape, (1) Bank amplifier for the purpose of preventing data loss on the magnetic disk (2) Large amounts of data storage (3) It becomes possible to distribute and move software and data.

B. As a recording/reproducing device: 1. With a magnetic tape, if the magnetic tape is held still and played back, for example, as in a still image, the magnetic tape will soon reach the end of its lifespan, but in the case of the present invention, the magnetic sheet on the disk side By transferring the information on the magnetic tape and using the flying head to reproduce still images, long-term playback is possible.

2. Since a transducer is provided on the recording medium disk to perform magnetic tape-to-magnetic disk conversion, that is, recording and reproduction, jitter can be significantly reduced compared to conventional techniques.

For example, as in the above-mentioned Japanese Patent Publication No. 43-21270 r periodic information signal reproduction method J, if the recording medium disk is located away from the rotating hent drum, vibrations due to shaft vibration, bearing vibration, and dynamic unbalance of the mechanical system will occur. Therefore, a time error occurs between the disk and the head drum, which causes jitter. However, the recording medium disk of the present invention has a recording medium and a transducer on the base, and does not have the same effect as the conventional rotating head drum. Because it can perform the same function as the conventional one, there is no effect of shaft vibration, bearing vibration, or dynamic unbalance. Therefore, there is no effect of jitter, and extremely good recording and playback is possible with no noise, unevenness, or code errors. became.
