Abstract
An optical disk drive includes a non-volatile memory. The optical disk drive is booted based on driving information stored in the non-volatile memory. When a write command is received from a host, the optical disk drive stores data to be recorded in an optical medium in the non-volatile memory and then writes the data in the optical medium independent of the host.
Claims19
An optical disk drive comprising:
- a controller configured to generate a first control signal based on driving information and a command received from a host;
- and
- a non-volatile memory configured to output the driving information and to buffer data received from the host and data read from an optical medium in response to the first control signal,
- wherein the controller determines, based on the command received from the host, whether to write data, which is received from the host, in the optical medium or the non-volatile memory and whether to read data from the optical medium or the non-volatile memory, and
- wherein the non-volatile memory both buffers data and functions as a separate storage device.

A method of operating an optical disk drive including a non-volatile memory, the method comprising:
- booting the optical disk drive based on driving information stored in the non-volatile memory;
- generating a first control signal based on a command received from a host;
- buffering data received from the host and data read from an optical medium in response to the first control signal;
- and
- determining, based on the command received from the host, whether to write data, which is received from the host, in the optical medium or the non-volatile memory and whether to read data from the optical medium or the non-volatile memory, and
- wherein the non-volatile memory both buffers data and functions as a separate storage device.
3 more elements
A method for accessing an optical medium comprising:
- generating a first control signal based on driving information and a command received from a host;
- outputting the driving information and buffering data received from the host and data read from an optical medium in response to the first control signal using a non-volatile memory;
- and
- determining, based on the command received from the host, whether to write data, which is received from the host, in the optical medium or the non-volatile memory and whether to read data from the optical medium or the non-volatile memory, and
- wherein the non-volatile memory both buffers data and functions as a separate storage device.
