Abstract

A removable magnetic storage device uses an optical drive interface to appear to the operating system as an optical drive. Thus, a removable magnetic drive appears to the operating system as a large optical device similar to DVD/CD, and receives similar functionality. By appearing as an optical device, the removable magnetic storage device can use many features not currently available to magnetic storage devices, such as autorun, multiple volume sets, larger capacity, and efficient space allocation.

Claims (17)

1. A method of interfacing with an operating system, the method comprising:

configuring a removable magnetic media system to use an optical drive interface to communicate with the operating system;

using an optical drive file system to enable communication between the removable magnetic media system and the operating system;

performing read and write operations to the removable magnetic media system using MMCs used by the optical drive file system; and

storing data on the removable magnetic media system in compliance with the optical drive file system.

2. The method of claim 1 , wherein the optical drive file system is the UDF file system.

3. The method of claim 1 , further comprising writing data to the removable magnetic media system in 64K allocations of 2K logical block addresses.

4. The method of claim 1 , further comprising automatically launching a program when media is inserted into the removable magnetic media system.

5. The method of claim 1 , further comprising supporting multiple volume sets.

6. A system for interfacing with an operating system, the system comprising:

a drive which receives a removable magnetic media cartridge; and

an optical drive file system to enable communication between the drive and the operating system,

wherein the drive is configured to communicate with the operating system using an optical drive interface, the optical drive interface configured to perform read and write operations to the removable magnetic media system using MMCs used by the optical drive file system, and the removable magnetic media system stores data in compliance with the optical drive file system.

7. The system of claim 6 , wherein the optical drive file system is the UDF file system.

8. The system of claim 6 , wherein the optical drive file system writes data to the removable magnetic media system in 64K allocations of 2K logical block addresses.

9. The system of claim 6 , wherein the optical drive file system automatically launches a program when a magnetic media cartridge is inserted into the drive.

10. The system of claim 6 , wherein the optical drive file system supports multiple volume sets.
