Disc with embedded flash memory and disc drive
View Patent ↗A disc has an outer section on which digital media can be recorded and a core in its center in which a flash memory is embedded with the core having a central hole and electrical contacts to the flash memory. A disc drive has a drive spindle that is to extend into the disc core central hole with one of the spindle or spindle hub having electrical contacts to engage with the core electrical contacts so that data can be written into and/or read from the core flash memory by electronic components of the drive.
1. A drive for a disc for digital media, said disc having an outer section on which data is recorded and an inner core having a central hole and an alignment tab extending into said central hole, said inner core including a flash memory with at least one electrical contact, said at least one electrical contact extending from said flash memory onto a peripheral wall of said inner core forming said hole, said drive comprising:
a drive spindle to extend into said central hole of said inner core, said drive spindle having a vertical slot to accommodate said alignment tab of said inner core; and
at least one electrical contact on an outer periphery of said drive spindle to engage said at least one electrical contact of said flash memory, wherein said vertical slot is configured to ensure alignment and engagement between said at least one electrical contact of said flash memory and said at least one electrical contact of said drive spindle.
2. The drive as claimed in claim 1 wherein said at least one electrical contact on said outer periphery of said drive spindle is in said slot.
3. The drive as claimed in claim 1 further comprising electronic components connected to said at least one electrical contact on said outer periphery of said drive spindle for reading data from and/or writing data into said flash memory on said disc.
4. The drive as claimed in claim 1 , wherein said at least one electrical contact on said outer periphery of said drive spindle comprises a plurality of electrical contacts.
5. A drive for a disc for digital media, said disc having an outer section on which data is recorded and an inner core having a central hole and an alignment tab extending into said central hole, said inner core including a flash memory with at least one electrical contact, said at least one electrical contact extending from said flash memory, said drive comprising:
a drive spindle to extend into said central hole of said inner core, said drive spindle having a vertical slot to accommodate said alignment tab of said inner core and a drive spindle base for supporting said disc; and
at least one electrical contact on said drive spindle base to engage said at least one electrical contact of said flash memory, wherein said vertical slot is configured to ensure alignment and engagement between said at least one electrical contact of said flash memory and said at least one electrical contact of said drive spindle base.
6. The drive as claimed in claim 5 wherein said at least one electrical contact on said drive spindle base is in said slot.
7. The drive as claimed in claim 5 further comprising electronic components connected to said at least one electrical contact on said drive spindle base for reading data from and/or writing data into said flash memory on said disc.
8. The drive as claimed in claim 5 , wherein said at least one electrical contact on said drive spindle base comprises a plurality of electrical contacts.
