Disc drive device

A disc drive device supporting at least two reading speeds, a high speed and a low speed, capable of driving a disc, reading data from the disc by following a read instruction from a host section, and sending the read data to the host section, the disc drive device comprising:

• a determining section operable to determine whether the disc has Real-time data thereon based on specific information stored on the disc;
• a managing section operable to set a flag indicating whether the Real-time data exists based on a determination result from the determining section;
• a processing section operable to read, from the disc at one of the reading speeds, the data corresponding to the read instruction;
• a storage section operable to temporarily store the read data;
• and
• a sending section operable to send the data stored in the storage section to the host section in predetermined playback timing, wherein
• the managing section sets the flag when the determining section determines that the disc has the Real-time data thereon, and
• when the reading speed is currently the low speed, the processing section keeps the reading speed while the flag is set.

A disc drive device supporting at least two reading speeds, a high speed and a low speed, capable of driving a disc, reading data from the disc by following a read instruction from a host section, and sending the read data to the host section, the disc drive device comprising:

• an extracting section operable to extract, from the read instruction from the host section, information indicating whether real-time playback is to be carried out;
• a processing section operable to read, based on the extracted information, from the disc at one of the reading speeds, the data corresponding to the read instruction;
• a storage section operable to temporarily store the read data;
• and
• a sending section operable to send the data stored in the storage section to the host section in predetermined playback timing, wherein
• when the reading speed is currently the low speed, the processing section keeps the reading speed while the information indicates that the real-time playback is to be carried out.
