Abstract

PURPOSE:To read plural data out by arranging plural data reading arms under individual control on the same surface of a disk medium on which data are recorded previously. CONSTITUTION:Plural read reading arms 2, 3, 4 and 5 are arranged on the same surface of the disk medium 1, and readout control parts 6, 7, 8, and 9 are connected thereto respectively. Those readout control parts 6, 7, 8 and 9 control them completely independently of one another. Consequently, the disk medium 1 rotates continuously in the same direction and the four data reading arms 2, 3, 4, and 5 reciprocate at right angles to the rotating direction of the disk medium 1 as shown by arrows; and the four readout control parts 6, 7, 8, and 9 move the corresponding readout arms 2, 3, 4, and 5 to radial positions on the disk medium 1 where read data are stored and also control reads of data from circumferential positions on the radii.

Description

データファイルの重要な手段であるディスク装置のデー
タ記憶ＳＮは、光デイスク媒体の出現等によシ飛躍的に
増大する傾向にるる。The data storage SN of a disk device, which is an important means for storing data files, has tended to increase dramatically with the advent of optical disk media.

Note that 6 is a readout control section here. In particular, in order to improve the data reading speed, there are systems in which multiple reading arms that are commonly controlled are arranged, but essentially the system is equipped with only one reading means. There isn't. There is a limit to the ability of such a single data reading means, and it is necessary to avoid creating a significant imbalance with the rapidly increasing storage capacity of disk media. Effective use of data is overdue.

本発明は大容量記憶ディスク媒体に整合しうる全く新し

ディスク装置を提供することにある。The object of the present invention is to provide a completely new concept of a disk device that can be adapted to large-capacity storage disk media, that is, a disk device equipped with a plurality of data reading means.

装置が得られる。According to the present invention, there is provided a disk device characterized in that a plurality of independently controlled data reading arms are arranged on the same surface of a disk medium in which data is previously stored.

次に本発明の一実施例について第２図を用いて説明する
。Next, one embodiment of the present invention will be described using FIG. 2.

るものである。FIG. 2 is a configuration diagram of an embodiment of the present invention, in which a plurality of data reading arms 2, 3, 4.5 are arranged on the same surface of the disk medium 1 as shown in FIG. Connect 6, 7, 8.9. These readout control units 6, 7, 8.9 can be controlled completely independently of each other.

．． 5 is perpendicular to the direction of rotation of the disk medium 10, and performs reciprocating motion as shown by the arrow. Also, four reading υ control units 6, 7, 8
．． Reference numeral 9 moves the corresponding protruding arms 2, 3, 4.5 to the radial position on the disk medium 1 where the read data is stored, and also controls the reading of data from the circumferential position on the radius. conduct.

本発明では、データの仇み出し系が複数個６Ｄその系が
互に独立であるので、回転するディスク媒体１から同時
に複数の独立したデータを読み出すことが出来る。In the present invention, since a plurality of data reading systems 6D are independent from each other, a plurality of independent data can be simultaneously read from the rotating disk medium 1.

一回転速度を有するディスク媒体に於いて、複数アーム
全体から同一時間当シ抗み出し得るデータ量は、従来の
単一アーム方式のアーム数倍となり、データ読み出し能
力の向上が著しい。This makes it possible to dramatically improve the data readability of the disk compared to conventional methods. In fact, for disk media having the same rotational speed, the amount of data that can be read out from all of the multiple arms at the same time is twice as many as the number of arms in the conventional single arm system, and the data reading capability is significantly improved.

本発明によれば、ディスク媒体の回転速度を上げること
