Flash Storage Virtual Optical Disc Recorder with Write Capability

Solution Overview

Problem

Traditional virtual optical disc recorders simulated by storage devices are limited to read-only functions, restricting their applications and failing to utilize multimedia capabilities fully.

Innovation Solution

A storage device with a flash memory divided into sectors for storing optical disc image files, parameters, and arbitrary data, where a controller reports the device as supporting burning functions, enabling the host to write data to the optical disc image file, mimicking a rewritable optical disc drive.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a storage device simulates a virtual optical disc recorder with read-only function, then the device can be simplified and manufactured easily, but the application range is limited and multimedia capabilities cannot be fully utilized

Engineering Contradiction:

Improveease of manufactureVSAvoidapplication range

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by enabling the virtual optical disc recorder to transition between read-only and read-write modes. The storage device can dynamically change its operational state based on user needs, allowing it to function as a read-only device for simplicity or as a read-write device for full multimedia capabilities, thus resolving the contradiction between ease of manufacture and application versatility.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent utilizes parameter changes by modifying the operational parameters of the virtual optical disc recorder. By changing the write-protection status parameter, the system can switch between read-only and read-write modes, enabling full burning functions while maintaining the simplicity of the storage device architecture.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If a storage device is designed as read-only virtual optical disc, then the data can be protected from accidental modification, but the user cannot update or change the contents of the virtual optical disc

Engineering Contradiction:

3Extent of automation

If a USB flash drive is configured as read-only optical disc drive, then the auto-run function can be implemented, but the burning function is lost and the optical disc drive range is limited

Engineering Contradiction:

Improveauto-run functionVSAvoidburning function

Core Design Contradiction:

Extent of automationVSAdaptability or versatility

Solution Approach 1:

The patent applies universality by designing the storage device to perform multiple functions: it can operate as a read-only virtual optical disc for auto-run functions, as a read-write virtual optical disc for burning operations, and as a standard flash memory storage device. This multi-functionality resolves the contradiction by enabling the device to provide both automated reading and writing capabilities through a single unified system.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Generating a virtual CD recorder by using a storage device is proposed. The storage device includes a first data sector for storing auto-run data and a second data sector for storing table of content (TOC) information data. When the storage device is connected to a host, a detecting module of the host detects whether the TOC information data exists in the second sector. When the TOC information data exists or could be accessed, a reading module can read a first disc image file based on the TOC information data. A burning module can record data into a second disc image file and update the TOC information data associated with the second disc image file in the second sector.
