Description

[0001] STORAGE DEVICE FOR DIGITAL CONTENT, IN PARTICULAR DIGITAL AUDIO CONTENT

[0002] The present invention relates to a storage device for storing digital content, in particular digital audio content.

[0003] The storage device according to the invention is particularly, although not exclusively, useful and practical in the distribution of music content, for example music albums, music collections, etc.

[0004] In any case, the digital content stored in the storage device according to the invention can also be video or audiovisual, in addition to audio. Therefore, basically, the storage device according to the invention can be considered a storage device for multimedia digital content.

[0005] Currently, storage devices of various types are known, which include for example memory cards, USB (Universal Serial Bus) flash drives, and external hard disks. However, these conventional storage devices are not devoid of drawbacks.

[0006] A drawback of these conventional storage devices consists in the fact that they need to be physically connected to a control device, for example a personal computer (desktop or notebook computer), in order to function, specifically in order to be electrically powered and to exchange data in input and / or output with the control device.

[0007] The physical connection between the conventional storage device and the control device can be direct or indirect. For example, this physical connection is direct for memory cards and USB flash drives, which need to be inserted into respective connection ports provided in the control device. And for example, this physical connection is indirect for external hard disks, which need to be connected to respective connection ports, provided in the control device, by means of a suitable connecting cable.

[0008] The physical connection described above implies that the conventional storage device and the control device must be in contact, for a direct physical connection, or at least in close proximity, for an indirect physicalconnection. Therefore, under no circumstances can the conventional storage device and the control device be at any distance from each other during the operation.

[0009] To solve this drawback and eliminate the need for a physical connection (direct or indirect), currently wireless external hard disks are known which can be connected to the control device through a short-range wireless communication network, for example a Wi-Fi network. However, these conventional wireless storage devices are also not devoid of drawbacks. In fact, they comprise an integrated internal rechargeable battery, which ensures a limited autonomy (for example 6-8 hours), and therefore needs to be recharged periodically using a suitable charging cable, and which considerably increases the weight of the device overall, rendering its use and / or transport inconvenient.

[0010] Another drawback of these conventional storage devices consists in the fact that they comprise at least one connector or at least one connection port in order to allow the abovementioned physical connection (direct or indirect) between the conventional storage device and the control device, or in order to allow recharging of the integrated battery of the conventional wireless storage device.

[0011] For example, USB flash drives comprise a USB connector to be inserted in a USB connection port of the control device, for direct connection with the latter. And for example, external hard disks comprise a USB connection port into which to insert one end of the connecting cable, with the other end of the connecting cable to be inserted in a USB connection port of the control device, for indirect connection with the latter. And for example, wireless external hard disks comprise a USB connection port into which to insert one end of the charging cable, with the other end of the charging cable to be inserted in a USB connection port of the control device, so that the latter will recharge the integrated battery.

[0012] This connector, or this connection port, render conventional storagedevices more vulnerable to shocks, which can cause breakage, and / or to external agents, for example dust or water, which can cause malfunctions.

[0013] The aim of the present invention is to overcome the limitations of the known art described above, by devising a storage device for digital content, in particular digital audio content, that makes it possible to obtain better effects than those that can be obtained with conventional solutions and / or similar effects at lower cost and with higher performance levels.

[0014] Within this aim, an object of the present invention is to conceive of a storage device for digital content that is versatile, i.e. that can be used in a plurality of applications, contexts or sectors.

[0015] Another object of the present invention is to devise a storage device for digital content that makes it possible to eliminate the need for a physical connection (direct or indirect), i.e. for a mechanical constraint, between it and a control device (or playback / recording device).

[0016] Another object of the present invention is to conceive of a storage device for digital content that makes it possible to eliminate the need for an internal integrated rechargeable battery.

[0017] Another object of the present invention is to devise a storage device for digital content that makes it possible to eliminate the need for a connector or a connection port.

[0018] Another object of the present invention is to conceive of a storage device for digital content that is durable and resistant, in particular to shocks and / or to external agents.

[0019] Another object of the present invention is to devise a storage device for digital content that is compact and lightweight, and is therefore comfortable to use and easy and economical to transport.

[0020] Another object of the present invention is to devise a storage device for digital content that makes it possible to protect the data stored on it, in particular from intrusion and / or abusive use.

[0021] Not least an object of the present invention is to provide a storagedevice for digital content that is highly reliable, easily and practically implemented, and economically competitive when compared to the known art.

[0022] This aim and these and other objects which will become more apparent hereinafter are achieved by a storage device for digital content, in particular digital audio content, according to claim 1.

[0023] The aim and objects are also achieved by a storage system according to claim 13.
