Description

Magneto-optical memory structure

Technical Field

The invention relates to the field of magnetic/optical disk memories, in particular to an optical magnetic memory structure.

Background

Conventional magnetic/optical disk storage and even early floppy disks were developed from early disc structures, which and their operating principles were: the motor located at the axle center of the disk drives one or more disks arranged at intervals with the axle center to rotate at a high speed ceaselessly, the magnetic head/optical head on each surface of the disk can move from the outer ring to the inner ring of the disk along the radial direction under the drive of the read-write arm, and the read-write arm moves the read-write head inwards a little after each circle of rotation of the disk so as to switch the data storage tracks of the inner ring and the outer ring, so that the data storage tracks are in a plurality of concentric circular rings or spiral lines. The data storage principles of magnetic disks and optical disks are based on magnetic storage technology and digital-optical recording and playback technology, respectively. With the increasing popularity of solid-state memory technology based on semiconductor memory principles, many people believe it will completely replace traditional magnetic/optical disk memory technology. However, in the application scenarios of long-term storage stability of data and high security requirements such as resistance to EMP attacks, the solid-state storage technology still far falls short of the advantages of the magnetic and optical storage technologies.

The inventors have found that the following problems and developing bottlenecks exist with the conventional magnetic/optical disk memory:

(1) the prior art further promotes the storage space difficulty: there are two general approaches to increasing storage capacity, one is perpendicular recording technology and the latest shingled magnetic recording technology, which are means of increasing the data storage density per unit area. However, the data storage density has reached the limit of the current technology, and increasing the data density may cause mutual interference between storage points; the shingled recording technology is a method for improving the storage space by sacrificing the data reading and writing speed and the data fault tolerance security, and the storage space is further improved by the method, namely the storage space is inverted at the end.

Another more direct approach is to increase the storage area, i.e. to increase the number of discs in a limited space. This not only increases the whole thickness and weight of memory, has still increased the load weight of motor for arm and light/magnetic head structure are more refined the processing degree of difficulty and are promoted, are influenced by the size of product and motor load capacity, and the quantity of disc also can not be infinitely increased. In order to ensure the rigidity of the disk, the scratch of the disk surface and even the burst of the disk caused by the axial vibration generated at the edge of the disk rotating at high speed can be avoided, and the thickness of the disk can not be further reduced.

(2) The reading and writing speed is slow: in the prior art, in order to meet the requirement of responding data random high-speed reading and writing in time, a disk needs to be always kept in a high-speed rotation state no matter whether a memory is in an idle state without data reading and writing; and the heat loss generated by the long-term high-speed rotation friction of the disk is more, the effective power of the system is lower, and the requirements of energy conservation and high energy efficiency ratio cannot be met. Even so, the data read-write speed still can not meet the requirements. In addition, due to the consideration of system robustness, process difficulty, control difficulty, cost and other factors, each surface of the storage disk can only be provided with one set of read-write arm and read-write head, and the improvement of the read-write speed is greatly limited.

The prior art is roughly divided into two directions for improving the data processing speed: one is by adding multiple levels of semiconductor-based memory technology cache in the control circuit. The other is a multi-memory array similar to the RAID structure of a disk, which essentially amounts to the addition of read and write arms and heads per disk surface to increase the amount of parallel data transfer. However, neither of these methods is a direct improvement of the internal structure of a single memory system, and there is no effective means for directly increasing the data processing speed with respect to the mechanical structure of a single magnetic/optical disk memory.

Detailed Description

The first embodiment is as follows:

the embodiment provides a magneto-optical memory structure which can be vertically installed, occupies a high space and occupies a small area; as shown in fig. 1, it comprises a mainframe 2, on which an array of storage disks 1 is mounted on the mainframe 2.

In the present embodiment, the main frame 2 has an H-shaped structure, and includes a support portion and a disk mounting portion, which is provided in a rectangular structure; the main frame 2 is used as a reference in a vertical state, the height direction is longitudinal, and the length direction is transverse; the supporting parts are symmetrically arranged at two transverse sides of the disk mounting part. In order to facilitate the installation of the slide rail, the support portion of the embodiment is configured to be an i-shaped structure. It is understood that the supporting portion and the disk mounting portion may be provided in other configurations in other embodiments.

Further, the cascade pieces 22 are respectively installed at the two longitudinal ends of the support part, and the cascade pieces 22 can prevent reverse insertion. The main frames 2 can be expanded in a cascading way along the height direction or the thickness direction and share one set of control system. In the present embodiment, the cascade member 22 includes a protrusion and a socket, and the end of the support portion has a plurality of insertion surfaces, for example, four insertion surfaces, as shown in fig. 1 and fig. 2, two insertion surfaces opposite to each other in the longitudinal direction and the thickness direction of the support portion are both provided with a protrusion, and the other insertion surface is provided with a socket with a shape corresponding to the protrusion. Of course, in other embodiments, the cascade member may have other structures or be disposed at other positions, as long as the installation of the memory structure can be realized.

Further, a signal interface 21 is arranged on the side surface of the supporting part. The disk mounting part is provided with a plurality of clamping grooves 23, and the clamping grooves 23 are distributed in a plurality of rows and a plurality of columns along the transverse direction and the longitudinal direction of the disk mounting part. The card slot 23 is used for placing the memory disc 1 and allows the card slot 23 to be vacant, i.e. not to place the memory disc 1. The embodiment expands the capacity of the memory by increasing the number of the memory disks 1 or inserting a plurality of main frame structures.

The storage disk 1 of the embodiment is static, moves through the relatively light read-write component 5, and only moves when data needs to be read and written, and does not need to be operated continuously, so that energy is saved, the problem of heat dissipation can be avoided, and the service life of each component can be prolonged.

Further, the main frame 2 is provided with first slide rails 3 on both sides, and in this embodiment, the first slide rails 3 are provided on both sides of each supporting portion symmetrical in the thickness direction of the disk mounting portion, and the first slide rails 3 are provided along the longitudinal direction of the main frame 2.

In this embodiment, a second slide rail 4 is connected between two first slide rails 3 located on the same side of the supporting portion, and one or more read-write assemblies 5 are mounted on each second slide rail 4; when a plurality of read-write components 5 are arranged on both sides of the main frame 2, the data parallel processing speed is higher.

When the plurality of reading and writing components 5 are mounted on the second slide rail 4, the adjacent reading and writing components are positioned on different sides of the second slide rail 4, namely, the reading and writing components positioned on the same side surface of the main frame 2 are arranged in a forward mounting mode (one side far away from the clamping groove 23) and in a reverse mounting mode (one side close to the clamping groove 23) in an alternating mode, so that the reading and writing components cannot collide when moving.

In order to further avoid the collision of the read-write components 5 on the same second slide rail 4 during the movement process, the second slide rail 4 is provided with an anti-collision limiting ring 41. The anti-collision limiting ring 41 is arranged between the adjacent reading and writing components 5, and when two reading and writing components 5 are arranged on the second slide rail 4, the anti-collision limiting ring 41 is arranged in the middle of the second slide rail 4 in order to ensure the stroke of a single reading and writing component 5.

In the present embodiment, a second slide rail 4 is installed between the first slide rails 3 for a detailed description, as shown in fig. 1, the second slide rail 4 is perpendicular to the first slide rails 3, that is, the second slide rail 4 is disposed along the transverse direction. The second slide rail 4 is connected with the first slide rail 3 through a moving block, and the moving block is connected with the first slide rail 3 in a sliding manner; the read-write component 5 can move along the length direction of the first slide rail 3 under the action of the moving block.

The reading and writing component 5 is connected with the second slide rail 4 in a sliding manner, and the reading and writing component 5 can move along the length direction of the second slide rail 4; that is, the entire pick-and-place unit 5 can move both laterally and longitudinally along the mainframe 2. In this embodiment, the movement of the moving block along the first sliding track 3 and the movement of the read/write assembly 5 on the second sliding track 4 can adopt a conventional motor driving structure. For example: a motor gear is arranged in the moving block, and a rack is arranged on the sliding rail; or the motor directly drives the threaded slide rail to rotate along the axis, and the corresponding threads are arranged in the moving block; and the like.

Wire grooves can be formed in the supporting portion and the second sliding rail 4, and flexible circuits or optical fibers can be used for signal transmission lines of all the components.

Further, as shown in fig. 3, the read/write module 5 includes a read/write head 55, an electromagnet 54, a connecting rod 52, a vibrating arm 53, a movable base 51, and a direct motion mechanism 56, where the vibrating arm 53 is a rigid sheet structure that can be bent toward the electromagnet, one end of the vibrating arm 53 is provided with a replaceable read/write head 55 and can be attracted by the electromagnet, and the other end of the vibrating arm 53 is mounted on one side of the movable base 51 through the linear motion mechanism 56; the other side of the movable base 51 is connected with the second slide rail 4 in a sliding way. The vibrating arm 53 is integrated with the electromagnet 54 through the connecting rod 52, and is driven by the linear motion mechanism 56 to move in a direction perpendicular to the second slide rail 4.

The linear movement mechanism 56 may be implemented by a conventional structure as long as the head 55 can be moved in the vertical direction. For example, the linear motion mechanism 56 is a rack and pinion mechanism, a plurality of gears are vertically arranged along the movable base 51 at intervals, a rack segment is arranged at one end of the vibration arm 53 far away from the read/write head 55, and the up-and-down movement of the vibration arm 53 is realized through the meshing action of the rack and pinion.

Further, one end of the movable base 51 is provided with a first limit block 58, and the other end is provided with a second limit block 57; the first stopper 58 is used to define the maximum protruding length of the vibration arm 53, and the second stopper 57 is used to define the shortest protruding length of the vibration arm 53.

In this embodiment, the second limiting block 57 is a protrusion structure, as long as it can limit the movement of the rack end of the vibrating arm 53; the first stopper 58 is composed of two protrusions having a spacing slightly larger than the thickness of the vibrating arm 53, and the spacing between the two protrusions is equal to the thickness of the vibrating arm 53, so that the vibrating arm 53 can be clamped without obstructing the extension and retraction of the vibrating arm 53.

Further, the vibration arm 53 is provided in a longitudinal direction, and one end thereof is provided with a mounting groove through which the read/write head 55 is mounted; the read/write head 55 passes through the mounting groove and is perpendicular to the vibration arm 53. The whole read-write assembly 5 can be disposed on the second slide rail 4 upward in the direction shown in fig. 3, or disposed on the second slide rail 4 downward in the direction. The pickup unit 5 is preferably oriented upward because the pickup head 55 is influenced by gravity to shorten the duration of the simple harmonic vibration generated by each electromagnet action when oriented downward, and the superposition of gravity when oriented upward helps to lengthen the duration, i.e., helps to save the electrical energy input to the electromagnets needed to maintain the simple harmonic vibration.

One end of the connecting rod 52 is connected with one end of the vibration arm 53 provided with the rack segment, and the other end is connected with the electromagnet 54. The whole of the vibration arm 53, the connection rod 52, the electromagnet 54, and the head 55 is moved in the vertical direction by the linear motion mechanism 56 to adjust the protruding length of the vibration arm 53, thereby adjusting the frequency of the simple harmonic vibration.

The shorter the arm length of the vibration arm 53 (the length extending out of the movable base 51), the faster the vibration, and the faster the scanning speed, thereby adjusting the speed of the read/write head 55 scanning the storage disk 1; the shorter the arm length, the shorter the period of energization of the corresponding electromagnet 54, and the greater the magnetic field required and the current strength of the direct current.

Further, the electromagnet 54 includes a magnetically permeable core 542 and an electromagnetic coil 541 wound around the outside of the magnetically permeable core 542. In this embodiment, the magnetically permeable core 542 is disposed on the radial side of the pickup head 55, and forms a C-shaped semi-surrounding structure for the pickup head 55; that is, the magnetically permeable core 542 forms an opening on both sides of the head 55, and the rest is closed.

The magnetically permeable core 542 can limit the magnetic path and reduce the influence of the leakage flux on the memory disk 1. The electromagnetic coil 541 can be wound on one end or two ends or the whole of the magnetic conductive iron core 542; preferably, an electromagnetic coil 541 is wound around one end of magnetically permeable core 542.

In addition, a metal casing may be disposed outside the reader/writer assembly 5 for packaging to further shield the electromagnet 54 from leakage flux. It should be noted that, when actually used, each component of the read-write assembly of this embodiment is packaged into a whole, and the whole memory structure is also packaged.

When the structure is used as a magnetic memory, the electromagnet 54 does not demagnetize the storage disk 1 or damage data due to the very strong coercive force of the magnetic field on the storage disk 1 and the limitation of the magnetic core and the metal packaging shell on the leakage flux; when used as an optical memory or other memory, the problem of magnetic field interference is not considered. The energy of the simple harmonic oscillation results from the periodic energization of the electromagnet 54. The vibrating arm 53 drives the read/write head 55 to vibrate in simple harmonic mode by periodically energizing the electromagnet 54, and the read/write assembly 5 moves transversely and longitudinally along the main frame 2, so that the read/write head 55 forms a serpentine data scanning track on the surface of the storage disc 1 as shown in fig. 4 (c).

The conventional magnetic disk data tracks are concentric circles as shown in fig. 4(a), and the conventional optical disk data tracks are spiral disks as shown in fig. 4 (b); the data track of this embodiment has a serpentine shape as shown in fig. 4 (c). The storage disk 1 of the present embodiment is configured to be rectangular, and the data tracks are formed by U-shaped structures that are sequentially connected end to end with the opening direction facing the side of the storage disk 1, that is, tracks synthesized by simple harmonic vibration in the horizontal direction and stepping motion in the vertical direction. To satisfy the synthetic trajectory shown in fig. 4(c), the vertical stepping frequency should be in a set proportion to the frequency of the simple harmonic vibration.

The circular track of the traditional magnetic disk can lead the lengths of the sectors of the inner and outer ring magnetic tracks to be different, thus bringing certain inconvenience for dividing the storage units. The tracks of this embodiment are approximately parallel straight lines, and the equal division of the length of the storage sectors is easily achieved.

The transverse distance of the track crossed by the simple harmonic vibration is equal to or slightly larger than the width of the storage disk 1, and the high-speed characteristic of the simple harmonic vibration is utilized to meet the requirement of the read-write head 55 for rapidly scanning and reading and writing data on the storage disk 1. Considering that the pickup head 55 is usually in a simple harmonic vibration state, the data transmission channel may be easily broken by long-time shaking if it is a conventional wire, the present embodiment uses an optical fiber or a flexible circuit as a data transmission path.

The data addressing and reading and writing method of the storage disk array described in this embodiment is as follows:

all the file allocation tables of the data on the storage disk 1 are stored in the first disk, as shown in fig. 5, the upper left corner of the storage disk array of this embodiment is the first disk, and of course, in other embodiments, the lower left corner, the upper right corner, the lower right corner or any other reasonable position of the storage disk array may also be the first disk.

The position coordinates of all the storage disks 1 mounted on the mainframe 2 will also be stored in the first disk or control system. In the case of sequential reading and writing, the vibration arm 53 carries the pickup head 55 to vibrate horizontally at simple harmonics, and the second rail 4 moves vertically downward or upward in accordance with the simple harmonics, so that the track on each disk has a serpentine shape.

As shown in fig. 5, in order to reduce the time wasted in switching between each row of storage disks 1 in the case of sequential reading and writing, the access tracks to different disks are in a continuous horizontal S shape, wherein the switching between the rows of storage disks is completed by the transverse movement of the reading and writing assembly 5 on the second sliding rail 4, and the start and end states of the transverse movement are preferably such that the longitudinal center line of the vibrating arm coincides with the longitudinal center line of the storage disk 1 on which it rests.

In the case of random reading and writing, the disk coordinates of the data to be read and the coordinates in the file allocation table are obtained from the first disk, and then the read/write head 55 is directly moved to the corresponding position to start the reading and writing operation.

Compared with the traditional structure, the embodiment has no high-speed rotating assembly, can easily expand the number of the storage disks and the reading and writing assemblies, and is convenient for expanding the storage capacity and increasing the reading and writing speed of a single magnetic/optical disk storage product; the problems of energy consumption, vibration resistance, heat dissipation, high sealing performance, high dust-free degree requirement and the like in the prior art are effectively avoided; the production process and the maintenance difficulty are reduced.

Example two:

as shown in fig. 6, the difference between the first embodiment and the second embodiment is that at least two second slide rails 4 may be distributed on the same side of the main frame 2, at least two read/write elements 5 may be distributed on each second slide rail 4, and two adjacent read/write elements 5 on the same second slide rail 4 are separated by an anti-collision limiting ring 41 disposed therebetween to avoid collision therebetween. If necessary, the bump stop ring 41 may also be mounted on the first slide rail 3.

Wherein, the mounting directions of two adjacent read-write components 5 positioned on the same side of the main frame are different, so as to avoid the edge collision of the two magnetic conductive iron cores 542.

The pickup head 55 of the pickup unit 5 having different mounting directions as described above has different lengths.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
