IPC: G11B20/10
Filed: 2001-03-19
Abstract: PROBLEM TO BE SOLVED: To perform a reproducing operation corresponding to a recording medium in which group management information is recorded. SOLUTION: When group management information for grouping recorded pieces of music is included in a disk name area constituting an area for the additional information of a recording medium as shown in a figure 3C, and when switching a group mode for successively performing signal reproduction in the group to a non-group mode for successively performing signal reproduction in the recording medium, the pieces of music in the recording medium is successively reproduced following the piece of music which is being reproduced. For example, when switching the mode during the reproduction of the name of a piece of music P4 in a figure 3A, the name of a piece of music P5 is reproduced.  When switching the non-group mode to the group mode, the signal reproduction in the group including the piece of music which is being reproduced is successively performed following the piece of music which is being reproduced. For example, when switching the mode during the reproduction of the name of a piece of music P7, the piece of music in the group GNb is reproduced. Thus, it is possible to perform the reproducing operation corresponding to the recording medium in which the group management information is recoded while maintaining the continuity of the reproducing operation even when operating the mode switching.

Title: Power supply circuit, display and electronic equipment
Inventor: YAMAZAKI TAKU
IPC: H02M3/07
Filed: 2001-03-28
Abstract: PROBLEM TO BE SOLVED: To stand a large current when a load is particularly large and reduce the loss in power consumption when the load is normally small in a charge pump and booster circuit using capacitors alternately charged and discharged. SOLUTION: A pre-booster circuit 4 and a post-booster circuit 6 sequentially boost a power supply voltage VCC and output voltages VEM, VOUT. An output voltage monitor circuit 8 monitors the voltage VEM. If the voltage VEM decreases, an instructing signal (up) for enhancing a boosting capability is outputted.
