Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a recording/reproducing device and its solid-state memory pack,
More specifically, the present invention relates to a recording/reproducing apparatus that selectively reproduces recorded information recorded on the image recording medium by loading a magnetic recording medium storage pack or a solid-state memory pack into the recording/reproducing apparatus, and the solid-state memory pack thereof.

[Prior Art] A subject image is formed on an imaging device such as a CCD, converted into an electrical signal, and after a certain signal processing is performed on this, the electrical signal is transferred to a flexible small disc-shaped 2. Description of the Related Art So-called electronic still cameras, which can perform magnetic recording on a rotating magnetic recording medium (hereinafter referred to as a magnetic disk) and reproduce images from the magnetic disk on a television or the like, are being put into practical use.

Next, we will introduce a flat, thin magnetic recording medium storage pack (hereinafter referred to as a disk pack) that stores the above-mentioned magnetic disk used in conventional electronic still cameras, etc., and a magnetic recording and reproducing device for this disk pack. The configuration of a magnetic disk drive device will be explained below.

As shown in FIG. 7, the disk pack 10 consists of a small disk-shaped magnetic disk 1 made of a thin flexible plastic plate or the like with a magnetic material attached by vapor deposition or the like, and a magnetic disk 1 made of a relatively hard plastic or the like. It is configured to be rotatably housed in a square jacket 2. A chucked member 1a for mounting is fixed to the center of the magnetic disk 1, and the central opening of the boss 1c of this chucked member 1a is connected to a magnetic disk drive device 20 (see FIG. 8) described below. The engagement hole 1b inserted into the output shaft 11a of the disk drive motor l for rotationally driving the magnetic disk 1 in
It becomes. This chucked member 1a is chucked by the chucking member 11b of the drive device 20. Further, on one side of the chucked member 1a on the back surface of the disk pack 10, there is a hole 2b through which the magnetic head 16 moves in the radial direction while contacting the recording surface (lower surface) of the magnetic disk 1. Further, on the surface of the disk pack 10, at a position opposite to the hole 2b,
The pad 12 provided in the magnetic disk drive device 20
(See FIG. 8) is provided with an opening 2a having the same shape as the hole 2b.

The magnetic disk drive device 20 to which the disk pack 10 configured as described above is removably attached has a substrate 13 made of a relatively thick iron plate, etc., as shown in FIG. A through hole 13a is provided in the middle shaft, and the output shaft 11 of the disk drive motor 11 is inserted into this through hole 13a.
a is inserted, and the motor 11 is fixed to the back surface of the board 13 by appropriate means. A chucking member 11b made of a permanent magnet or the like for chucking the chucked member 1a of the magnetic disk 1 is provided at the tip of the output shaft 11a. Further, a stepping motor 14 for moving the magnetic head 16 is disposed on the substrate 13 to the right of the hole 13a, and an output shaft 14a of the motor 14 has a radius of the disk 1. One end of a rod-shaped feed screw 14b, which is disposed in the same direction and has a male thread on its circumferential surface, is directly connected to the feed screw 14b. The other end of this feed screw 14b is connected to a bearing 1 disposed near the hole 13a.
3b is rotatably supported. Also, below this feed screw 1.4 b is the same screw 1.4. A guide shaft] 5 is horizontally suspended parallel to b. Then, the guide hole 7a formed in the support 17 (see FIG. 9(A)) to which the magnetic head 16 is fixed is inserted into the guide shaft 15, and the feeder is inserted into the threaded hole 17b having a male thread. A screw 14b is engaged, and the rotation of the stepping motor 4 causes the magnetic head 16 to move intermittently in the radial direction while slidingly contacting the recording surface of the magnetic disk 1.

Further, above the substrate 13, a holding member 18 made of a relatively thin iron plate or the like is disposed at a predetermined interval in parallel to the substrate 13 and can be raised or lowered. The disc pack-0 is loaded into the internal space 23 formed by the disc pack-0. That is, the presser member 18 is provided on the upper surface of the right portion of the substrate 13.
A column 19 is disposed for supporting the presser member 18, and a supporting shaft 19a is provided at the tip of the column 19 to support the holding member 18.
The right end portion of is rotatably supported. A compressible coil spring 21 is stretched between the support column 19 and the right side of the holding member 18, giving the holding member 18 the habit of rotating counterclockwise. . However, this rotation due to this habit is prevented by the lower surface of the left tip of the presser member 18 being blocked by the support 22 installed on the upper surface of the left portion of the base plate 13, and thereby The above-mentioned internal space 23 is secured.

A portion of the rightward inner surface of the holding member 18 facing the movement range of the magnetic head 16 is provided at a predetermined distance from the magnetic head 16 so as to be parallel to the movement of the magnetic head 16. The pad 12 is provided. This pad 12, as shown in FIGS. 9A and 9B, is formed of a slightly thick rectangular plate member, and its depth is greater than the moving distance of the magnetic head 16. Kudzu is slightly longer. This pad 12 is provided with a groove-shaped recess 12a in the center of its lower surface in the same direction as the moving direction of the head 16, so that when the head 16 moves in sliding contact with the magnetic disk 1, the head The disc is designed to release the bulge caused by pressure contact. Furthermore, vertically long rectangular flat surface portions 12b12c are formed on both left and right sides of the four portions 12H, and the surface roughness of these flat surface portions 12b and 12c is finished with high accuracy.

The magnetic disk drive device 2 configured as described above
To load the disk pack 10 (see FIG. 7) into the disk pack 0, first rotate the presser member 18 clockwise to open the space 23, and then open the space 23 so that the opening 2a of the disk pack 0 is inserted into the pad 12. The pack 10 is placed at a predetermined position on the substrate 13 so that they fit together. At this time, the pack 10 is positioned parallel to the substrate 13. When the pack 10 is arranged in this way, as shown in FIG.
and a chucking member provided at the tip of the disk drive motor 11], 1b are combined, and the magnetic disk 1 is rotated by the motor 11. When the presser member] 8 is closed, loading is completed.

That is, in this state, it becomes possible to record on the magnetic disk 1 by an electric control circuit (not shown).

Therefore, in the loaded state of this disk pack 10,
Now, when the electric circuit is operated, the drive motor 11 rotates at a high speed of, for example, 3600 RPM in response to a control signal from a control circuit (not shown). Then, if the magnetic disk 1 also rotates at the same speed, or if the rotational speed increases beyond a certain speed, the disk 1 and the pad 1 rotate at the same speed.
A stable air layer 24 (see FIG. 9(A)) is formed between the disk 1 and the magnetic pad 12 and the jacket 2 (see FIG. 7). It comes into sliding contact only with the head 16 with a predetermined contact pressure. In other words, a predetermined control circuit allows recording and reproduction to be performed only in the stable sliding contact state as described above. Note that by driving the stepping motor 14, the magnetic head 16
For example, it moves in the radial direction of the above-mentioned disk at a pitch of 100 μm, and performs recording and reproduction at a predetermined position.

In order to load the magnetic recording medium storage pack 10 configured as described above into a recording/reproducing device, a plurality of packs are normally stored in the magazine of an autochanger, and a desired pack is selected from among the packs into the autochanger. It is designed to be selected by the mechanism and automatically loaded into the recording/playback device.

[Problems to be Solved by the Invention] However, when a plurality of magnetic recording medium storage packs are stored in such an autochanger, it becomes unclear what has been recorded on the magnetic recording medium in each pack. Therefore, a separate index for the storage pack is required. Therefore, it is preferable to prepare one memory pack for indexing separately from the plurality of magnetic recording medium storage packs, and to record the recorded contents of the plurality of magnetic recording medium storage packs in the same memory pack.

Such an index memory pack must be able to be accessed at high speed, and its recorded information must be immediately readable even when mixed with a plurality of magnetic recording medium storage packs. Therefore, by slightly modifying the same storage container as the magnetic recording media storage pack and loading IC memory such as ROM into the container to create a solid memory pack, not only high-speed access is possible, but it can also be directly inserted into the disk drive device. This eliminates the need for a card insertion/removal mechanism, and allows the recorded information to be read immediately by simply inserting the card into the disk drive of the magnetic recording medium storage pack.

In contrast, conventional magnetic recording medium storage packs are not suitable for large-capacity recording, that is, for recording information on about 50 still images, or for high-speed reading and writing.

Therefore, it is unsuitable for packs for indexing, for example.

Therefore, an object of the present invention is to provide a magnetic recording medium storage pack,
To provide a recording/reproducing device which can be loaded with any solid memory pack.

Means for Solving the Problems] The recording/reproducing device (recording device, reproducing device recording and reproducing device) of the present invention includes a pack loading section capable of selectively loading a magnetic recording medium storage pack and a solid memory pack. Further, in the solid state memory pack of the present invention, the storage container has a head entry section, a rotary drive member entry section, and an electrical connection section.

E-Function This solid-state memory pack is provided with a head entry section, a rotary drive member entry section, and an electrical connection section, but when the solid-state memory pack is loaded into the pack loading section of a recording/playback device, Even if an attempt is made to connect, for example, a chucking mechanism of a magnetic head or a magnetic recording medium rotation driver, the solid-state memory pack does not have a corresponding mechanism, so it cannot be connected magnetically or mechanically. However, since electrical connections are formed at the tip of the solid-state memory pack and the corresponding locations of the recording/reproducing device that come into contact with the tip, these are electrically connected.

On the other hand, if a magnetic recording medium storage pack is loaded into the pack loading section of this recording/reproducing apparatus, it will be magnetically connected in the same way as the conventional one shown in FIGS. Since there is no electrical connection at the corresponding part on the magnetic recording medium storage pack side corresponding to the electrical connection, there is no electrical connection.

In other words, in this recording/playback device, the magnetic recording medium storage pack and the solid-state memory pack are either housed in a storage container with the same shape, or they are connected magnetically, so that the information recorded in the magnetic recording medium storage pack can be transferred electrically. By connecting to the solid-state memory pack, the recorded information is selectively accessed.

[Example] The present invention will be specifically described below with reference to the drawings. In the present invention, as described above, the recorded information stored in the magnetic recording medium storage pack and the solid-state memory pack is accessed by the recording/reproducing device by selecting whether to use a magnetic connection or an electrical connection. ing. this house,
The mechanism for accessing the recorded information stored in the magnetic recording medium storage pack through magnetic connection and its operation have been described in detail in the conventional example shown in FIGS. We will only explain the memory pack and its operation.

FIG. 1(A) is a perspective view of a solid state memory pack showing one embodiment of the present invention. In the figure, solid state memory pack 3
is the same storage container as the magnetic recording medium storage pack shown in FIG. ROM installed with
An IC memory ME such as the following is stored. A magnetic recording medium storage pack 10 (
This is the hole in which the boss 1c is disposed in (see Fig. 7),
A rotary drive body entry part 4 consisting of a circular hole is bored,
A head intrusion part 5 consisting of a horizontally long rectangular N through hole is formed above the intrusion part 4 in the figure.

When the solid-state memory pack 3 is loaded into the magnetic disk drive device 20 shown in FIG. 11 output shafts 11
The chucking member 1.1b disguised as a enters into the rotary drive body entry section 4, and the stepping motor 1
The magnetic head 16 interlocked with the magnetic head 4 enters the head entry section 5, and both the chucking member 11b and the magnetic head 16 that enter the entry section 45
Its size is set so that it can move freely within the space. In other words, when the solid-state memory pack 3 is loaded into the pack loading section of a recording/reproducing device, the rotary drive body and magnetic head used in the magnetic recording medium storage pack enter the solid-state memory pack 3. Formed as an escape hole.

When loaded, the solid memory pack 3 is configured to slide in the direction of arrow A while its left and right sides 3b, 3c are supported by guide pieces (not shown). Therefore, avoiding the side surfaces 3b and 3c that slide with this guide piece and the rear surface 3d where the connection is likely to be unstable, at least three electrical contacts 6a forming the electrical connection part 6 on the tip surface 3a,
6b6c is formed. These contacts 6a and 6b are for sending and receiving signals, and the -5 contact 6C is for sending and receiving signals.
As shown in Figure (B), the tip surface 3a of the solid memory pack 3
It is bent into an L-shape from the top surface to the back surface 3e, or from the tip surface 3a to the front surface 3f as shown in FIG. It is buried in such a way that it becomes like this.

This is to prevent the contacts from peeling off when the device is installed in the pack loading section, and one should be selected depending on the loading condition.

FIG. 2 shows the state in which the solid-state memory pack 3 is loaded into a front-loading type recording/playback device, and FIG. 3 shows the state in which the solid-state memory pack 3 is loaded into a top-loading type recording/playback device. In FIG. 2, when the fixed memory pack 3 is inserted from the distal end surface where the electrical connection portion 6 is disposed along the arrow B from the insertion opening (not shown), the pack 3 reaches a position 3A indicated by a dotted line. Thereafter, it descends directly downward as shown by arrow C, and stops at the normal loading position, that is, when it comes into contact with the disk drive motor 11. In this position, the electrical connection part 6 of the solid bank 3 is connected to the electrical connection part 7 disposed in the magnetic disk drive device in the recording/reproducing apparatus corresponding to this connection part 6.
It will be electrically connected to A.

In the case of top loading shown in FIG. 3, the solid state memory pack 3 is inserted from the distal end surface where the electrical connection part 6 is provided through the pack insertion opening (not shown) along the arrow, as shown by the dotted line. As shown, the memory pack 3 is pushed down at the position where the connection part 6 at the tip of the memory pack 3 comes into contact with the electrical connection part 7B provided on the magnetic disk drive device in the recording/reproducing apparatus, and the memory pack 3 is moved to a horizontal position. to be transferred to Then, the electrical connection section 6 of the solid-state memory pack 3 is electrically connected to the electrical connection section 7B in the recording/reproducing device.

By the way, when the solid-state memory pack 3 is not loaded in the pack loading section of a recording/reproducing device, the contact surface of the electrical connection section 6 of the pack 3 is exposed to dust and dust in the atmosphere. In addition, the contact surface may become dirty due to operator's carelessness and may cause contact failure.

The present invention takes this into consideration, and a shirt shirt plate that automatically opens and closes in response to loading into the pack loading section is used to protect the contact surfaces. The shirt plate originally had holes 2a in the magnetic disk pack.

2b (see FIG. 7), or is provided in the same manner as the shirt top plate thereof.

FIGS. 4(A) and 4(B) show the solid-state memory pack 3.
2 is a perspective view of a shutter 8 that protects and immerses the contact surface of the electrical connection portion 6 in the figure. (8) shows a state in which the shutter 8 covers the contact surface, and (B) shows a state in which the shutter 8 is open. As mentioned above, the magnetic recording medium storage pack includes a rectangular opening 2b (see Figure 7) for sliding the magnetic head to the medium surface, and a protection to prevent dust from entering through the opening. A shirt board is provided for use. Therefore, in this embodiment, the electrical connection part 6 is disposed on the upper surface of the pack 3, and in order to be able to shield the connection part 6, a shirt top plate 8, which is larger than the normally used shirt top board, is used. This shirt cover plate 8 opens and closes the head entry section 5 at the same time.

Figures 5(8) and (B) show that the top surface of the tip of the storage container of pack 3 is the largest number of signals input and output from the IC memory ME.
In the case where a large number of terminals 6a to 6e are arranged across the cup,
In this case, the shirt top plate 8A is provided at the width of the container. And such shutter plates 8, 8A
The opening/closing mechanism uses the same means as the well-known shutter opening/closing mechanism for protecting the aperture for sliding the magnetic head in the magnetic recording medium storage pack.

In this embodiment configured as described above, when the solid-state memory pack 3 is loaded into the pack loading section of the recording/reproducing apparatus, the rotary drive body and the magnetic head of the recording/reproducing apparatus each drive the rotation of the solid-state memory pack. It invades the body intrusion part 4 and the head intrusion part 5. However, since both the entry portions 4 and 5 are escape holes, no magnetic connection is made.

On the other hand, the electrical connection section 6 of the solid-state memory pack 3 is electrically connected to the electrical connection section 7A or 7B of the recording/reproducing device, so that the IC memory ME such as ROM mounted on the solid-state memory pack 3 is supplied with power. is supplied and the output signal is read out.

On the other hand, when the magnetic recording medium storage pack 10 is loaded into the pack loading section, no electrical connection is made because the storage container of the magnetic recording medium storage pack 10 is not provided with an electrical connection section. As explained in the conventional example above, the rotation of the disk drive motor 11 is transmitted to the magnetic disk 1, the disk 1 rotates, and recorded information is read from the magnetic head 16 that is in sliding contact with a predetermined track. It will be done.

In other words, a signal output can be obtained through magnetic connection.

In the above explanation, the electrical connections of the solid state memory pack 3 are as follows:
This is done using the electrical connection part 6 provided at the tip of the pack, but by using the accidental erasure prevention claw 9 shown in FIG.
A contact point may be provided near the erroneous erasure prevention claw 9 and used for sending and receiving signals, storing and writing instructions, etc. Also,
A protective cover 9a is provided on this accidental erasure prevention claw, and by sliding this protective cover 9a, it is possible to prevent atmospheric dust and the like from adhering to the contact surface.

Further, in the above explanation, the SVF used in an electronic still camera was used as an example, but the present invention is not limited to this, and can of course be applied to, for example, a floppy disk having a 3.5-inch hard case. It is.

Furthermore, if the present invention is applied to a recording/reproducing device having an autochanger mechanism, the solid-state memory pack can be used for indexing and 1. Since it can be used in , high-speed search is possible and effective.

[Effects of the Invention] As described above, according to the present invention, a magnetic recording medium storage pack can be used when storage of human melons is required, and a solid-state storage pack can be used for retrieval that requires ultra-high-speed access. Since a memory pack can be used, a remarkable effect is achieved in that it can be used in the most flexible way depending on the application.
