with no manual involvement of the user other than inserting the removable flash memory digital recording medium into a plug assembly in said recording device."
There are issues within that phrase that are spelled out in the "DETAILED DESCRIPTION OF THE INVENTION"
Specifically, for marking memory segments of bad memory so that data is not stored in bad memory spaces.
If you have not reviewed the 737 details...for the marking of bad memory cells...
per fig 3A
"Step 2 designated 220 is the entire memory integrity verification process. The user slides the flash memory into its slot in the recorder. After a few moments, both the green 60 and red 61 LEDs light. A few moments later, a tone sounds and the LEDs 60 and 61 are extinguished. While the LEDs were both lit, the integrity of the memory segments of the flash memory unit were tested. If any of the memory is found to be defective, the segment is marked. The recorder will not attempt to record to or read from a memory so marked. Therefore, no portion of a memory segment can be lost by erroneously recording to memory that was defective before the message was recorded. An alternative method for causing the same verification of flash memory to be executed is accomplished by removing the batteries, and then reinstalling them. The recorder will run the same memory integrity verification.
FIG. 3B is a diagram of the flash digital memory structure used in the present invention. The box 230 represents a possible division of memory into messages, unused memory segments, and defective media that is not marked as defective. Box 240 reflects the actual memory structure after the memory integrity verification process has been executed, leaving the formerly defective but unmarked memory segment marked as defective. Functionally, the memory appears as shown in box 250. The defective marked media is simply ignored and does not interfere with recording or playing messages"
"The defective marked media is simply ignored and does not interfere with recording or playing messages."
That phrase is important, because it represents how the data and the bad memory stay out of each others way.
They stay out of each others way in the same way data in general stays out of each others way.
Same principle is used.....bad memory is treated like data, though the metadata used over bad memory is specific....orchestrating the memory area as "unviable marked media"
All this happens under the hood, without the user doing anything by way of having to do any pre configuration formatting ....all the bad media is organized....and the memory is ready for programming data.
Other considerations found in "OBJECTS AND SUMMARY OF THE INVENTION " as equally important:
"Also disclosed is a method for recording a new message without disturbing the physical continuity of existing messages and without manually searching for a blank segment of memory on the recording medium which includes the steps of"
The underlined condition is a direct result of what happens under the hood as well...
For others utilizing standard methods of flash management(the under the hood stuff)....they can not make that statement...as they do those things.
"The defective marked media is simply ignored and does not interfere with recording or playing messages."
anyway
doni
With that phrase, e.Digital only nail them on the bad memory issue and they get the whole issue resolved for data management.
