The present invention relates to a stack type multi-optical disk input / output device having a large capacity optical pickup unit.

More specifically, a stack-type multi-capacity optical pickup unit having a large capacity support optical pickup unit for providing multiple accesses by providing an optical pickup device capable of removing a disk changing device, which is an essential component for reading or recording data recorded on a double-sided optical disc. An optical disk input / output device.

In line with the information age, information demand is increasing more than 1000 times every five years. Nowadays, the information storage field is becoming a new industrial field. Among these, as the corporate computer environment changes rapidly based on the network, a mass storage device capable of storing and managing a large amount of data is in the spotlight. This was also influenced by the emergence of data-intensive systems such as data warehouses and enterprise resource management as the corporate network environment spread. In response to this trend, demand for storage devices is growing explosively, with the introduction of such data-intensive systems, especially in government offices, corporations, financial institutions, and telecommunications companies.

In addition, a multi-terabyte storage medium is created by electronic libraries, business intelligent, VOD services, hospitals / public institutions, music services, large web servers, home servers, etc., which are expected to form a new market. Is even more demanding.

In the United States, the online supply of music contents using the Internet has already become a trend, and is preparing for the joint development and commercialization of digital movie distribution systems for movie theaters. Therefore, with this global trend, the network storage sector is changing the server-centric market and forming a huge storage-oriented market.

The storage media corresponding to the classification can be classified into semiconductor memory, tape storage, magnetic storage, and optical storage. In the main server storage device, HDDs are easily used among magnetic storage devices with easy data random access and fast retrieval time. Tape storage and optical disk I / O devices are competing as storage media for large data storage. Until now, large-capacity and low-cost tape storage has taken the lead in the price / capacity capacity and occupy the leading network storage market. However, the tape storage has disadvantages in terms of retention period, data accessibility, and data loss rate. There is a problem.

On the contrary, optical disk input / output devices (optical jukebox) using optical storage have a comparative advantage in terms of stability and data accessibility compared to tape storage, and have been developed into a large capacity storage device such as tape through the development of disk manipulation mechanism. In addition, based on the continuous expansion of disk capacity and price, it is emerging as an alternative to the most promising mass storage device in the future as an storage medium for archiving.

As optical jukeboxes have emerged as the focus of the archival storage market, the related product groups currently forming in the market are not much different and are similar. Basically, the DVD-type drive can be selectively installed in a structure, and the disc can be stored in a box in a limited capacity and automatically recorded therein. Therefore, since the basic optical storage device is used as it is, the storage density, the recording type, the time, etc. are all the same, and the disk storage and the disk transport mechanism are different as the main technologies.

Such techniques are referred to as disk changing mechanisms, picker mechanisms, and the like. As a result, data storage and retrieval time influence one of the core technologies of an optical disc input / output device (Optical jukebox). However, since the existing personal drive is used as it is, there is a limit to an efficient storage medium in terms of additional price and capacity.

Currently, the disk changing mechanism has two types. One is the main form, which arranges the disk and the drive horizontally to transport and precisely arrange them. The other is divided into a mechanism for arranging the disk and the drive in a desired form and placing the disk in the desired drive.

The difference between the two mechanisms is configured as needed in terms of overall size, capacity and efficiency. The two mechanisms require a belt system that carries the disk and a changing mechanism technique that flips the disk to read the double-sided disk. Another important technique involved is the picker mechanism for picking up discs. The picker mechanism is a technology of recognizing and picking up a disc. Currently, the picker mechanism is introduced by incorporating a disc flipping technique into the picker mechanism.

Currently applied optical jukebox is a system that can search one disk at a time, and it is expensive to build additional drives to compensate for this, and it takes a lot of time to transfer and search for data. This is a useful and largely unreasonable problem in terms of size.
