Abstract

The present device for writing/reading data relates to the field of computer technology, and more particularly to devices for writing/reading data. The device for writing/reading data functions as follows. More than one write and/or read head is disposed on a positioning means in proximity to one and the same surface of a rotating medium. Data exchange occurs for all of the write and/or read heads simultaneously or at random. Suggested arrangement: in proximity to one and the same surface of a rotating medium, a positioning device is situated which simultaneously positions write and/or read heads attached thereto onto the appropriate regions of said rotating medium. When two or more write and/or read heads are placed over one and the same surface, they move simultaneously on one and the same positioning means (for example, an arm). In addition, in order to facilitate mutual alignment of the write and/or read heads, the part of the surface of the rotating medium that is intended to receive information can be divided into conceptual sections by means of technical gaps such that each of the write and/or read heads moves in proximity to one conceptual section only, the number of sections being equal to the number of write and/or read heads. The claimed technical solution increases the average data access speed and data transfer speed, thus solving the problem of interest.

Description

Device for writing / reading information

The invention relates to the field of computer technology, namely, devices for recording / reading information.

From general knowledge ["Secrets of the hard drive." Kiev: "Dialectics", 1994. - 256 s, ill.] It is known about placing one recording head near the same surface of a rotating medium in devices such as optical or magnetic disk drives.

The closest technical solution to the claimed invention and adopted as a prototype is the technical solution "DEVICE FOR STORING INFORMATION" (patent US3,007, 144 dated October 31, 1961 IPC G 1 1B 17/26 (20060101); G1 1B 21/08 (20060101 ); G1 1B 5/55 (20060101); G1 1B 5/596 (20060101); G 1 1B 17/02 (20060101); G1 1B 17/038 (20060101)), which describes a device that uses a relatively small number of sensors - converters (heads) relative to the number of tracks (sections) of storage [data], while the heads can be arbitrarily positioned into sections.

The device includes a plurality of magnetic disks (rotating media) that rotate together on a common axis and a head associated with each surface of the disk.

Different heads are connected for joint controlled movement to selected tracks (sections), and switching is provided in such a way as to bring the heads associated with specific tracks (sections) into working condition.

From the known it is obvious that the existing technical solutions have a lower average data access speed and data transfer rate in comparison with the claimed invention.

The disadvantages of the prototype include the fact that the location of only one head near one surface of the disk (rotating media) causes a loss of time when repositioning the head between different tracks (sections).

The basis of the invention is the technical task to increase the average speed of access to information and the speed of information transfer in devices with rotating media (for example: hard drives, CD-ROMs, etc.). The technical task is solved in the following way. More than one recording and / or reading head is placed on the positioning means near the same surface of the rotating medium. Information exchange is carried out for all recording and / or reading heads simultaneously or arbitrarily.

The essence of the invention is explained by the drawings, which show:

In FIG. 1 - Diagram of a device for recording / reading information;

In FIG. 2 - An example of placing at least two heads of recording and / or reading information.

Suggested location: near the same surface of the rotating medium, a positioning means is placed that simultaneously positions the recording and / or reading heads attached to it on the desired sections of the rotating medium. As shown in FIG. 1 and FIG. 2, a device for recording / reading information contains: a rotating medium (the form is shown conditionally) 1, a part of the surface of the rotating medium, which is intended for the location of information 2, the technological gap (optional) 3; positioning means with recording and / or reading heads 4; the axis of rotation of the rotating medium 5; individual sections that are intended for the location of information (numbering conditional) 6; recording and / or reading heads (numbering conditional) 7.

The claimed technical solution works in this way.

When two or more recording and / or reading heads 7 are placed on the same surface 2 on the same positioning means (for example, an arm), they move simultaneously, as shown in FIG. 1, FIG. 2.

Additionally, to reduce the cost of adjusting the relative position of the recording and / or reading heads, the part of the surface of the rotating medium that is intended for the location of information can be divided into conventional sections by technological intervals so that each of the recording and / or reading heads moves only near one conditional sections, and the number of conditional sections is equal to the number of write and / or read heads.

Suppose the time of repositioning the recording head and / or reading from section n, which is designed to place information on section n ± 1, is 1, the number of sections T is 24. The time required for repositioning from baking section, which is designed to locate information on section p _The requirement for the prototype will be as shown in the table. one. Tab. one

For the prototype, with a uniform distribution of requests for repositioning between all sections and with the number of requests G ² , 4,600 units of time will be needed.

Consider an example where the number of bits N of recording and / or reading equals the hook 3. In the event the time required for repositioning a portion _TEKU n u _and d, which is intended for location information on n _tre portion b _uemY minutes with the proposed placement will be as in table 2. For this arrangement, with a uniform distribution of requests for re-positioning between all sections and with the number of requests C, 1512 units of time will be necessary, which is 67.13% less than for the prototype.

Additionally, the recording and / or reading of data can be performed on / from all recording and / or reading heads at the same time, which increases the data transfer rate to / from the rotating medium in Hpa3. Tab. 2

As a result of the implementation of the claimed invention:

increased average data access speed and data transfer rate. It coincides with the technical task.
